MapGIS builds a sturdy 'fortress' for earthquake resistance in Hainan
Life is precious to people, but in recent years, earthquakes have occurred frequently in China, causing many casualties. The pain of Wenchuan five years ago and the sorrow of China are deeply engraved in the hearts of every Chinese person; The Ya'an earthquake in April this year, the loss of fresh lives one by one, made us heartbroken... Faced with the earthquake, is humanity really powerless?
The answer is definitely negative! With the development of information technology, the use of 3S technology for disaster prevention, reduction, and relief has achieved good results, and GIS technology has played an indispensable role in earthquake resistance. After the Ya'an earthquake, domestic 3S companies contributed money and effort, composing a beautiful hymn of industry disaster relief and love. Gaode Map, Digital Space, Tianxia Map and other geographic information service providers actively seek and volunteer. National units such as the National Bureau of Surveying, Mapping and Geoinformation Technology and the Institute of Remote Sensing of the Chinese Academy of Sciences also responded quickly, winning valuable rescue time to save lives and property. Zhongdi Digital, a leading GIS development platform and solution provider in China, has quickly built a 3D Earth GIS website with real-time route maps, real-time zoning of casualties, rescue station information, news, on-site images, and other functions to time life. 0.16-meter aerial images and 30 meter elevation data also provide auxiliary support for decision-making. The rapid construction of the website provides strong technical support for disaster area construction. They are using technology to save lives, using technology to make every life respected.
In fact, the Hainan seismic fortification full process supervision platform based on MapGIS has shown its initial strength in earthquake prediction and disaster reduction. This system is at the forefront of earthquake prediction informatization and has caused a good response within the earthquake system. To investigate, the reporter visited Wu Tiesheng, a senior engineer at the Hainan Marine Seismology and Engineering Seismology Research Center.
Wu Tiesheng, a senior engineer, mentioned that Hainan Island is surrounded by the sea on all sides and is located at the southwest end of the seismic belt along the southeast coast of China. As early as 1605, a 7.5 magnitude earthquake occurred here, and the problem of earthquake prevention and disaster reduction is more complex than inland areas. Therefore, it is particularly urgent to build a seismic fortification supervision platform and effectively enhance the seismic fortification capacity of buildings (structures). At the same time, we cannot rely on chance to prevent earthquakes. The focus of earthquake prevention and disaster reduction work should be on strengthening seismic fortification supervision. The "Hainan Province Seismic Fortification Requirements Full Process Supervision Technical Service System" project was launched in this context. After more than a year of construction, it was officially put into operation after passing acceptance and trial operation in 2012. This is also the first MapGIS based full process supervision platform built in Hainan.
The "Hainan Seismic Fortification Requirements Full Process Supervision Technical Service System" currently in operation demonstrates the powerful power of informatization. This platform supports large capacity databases, with efficient storage and indexing capabilities for massive spatial data, as well as the ability to process TB level spatial data, and can withstand a large number of concurrent user accesses. In addition, through the data processing function of MapGIS, the system has achieved unified and comprehensive management of earthquake thematic data, including large-scale zoning data, small-scale zoning data, active fault data, sand liquefaction data, soft soil seismic subsidence data, earthquake induced landslide data, shelter data, earthquake monitoring facility data, engineering site data and other seismic fortification elements. The data is very extensive and comprehensive, meeting the application requirements of approval support and filing supervision business.
The full supervision platform utilizes the powerful spatial analysis function of MapGIS to achieve automation of seismic fortification requirements and judgments. Users only need to input the coordinates of the engineering site range to immediately provide the seismic parameters and environment of the project; It can also automatically provide the seismic geological hazard environment of the project, including the spatial distribution relationship with earthquake landslides and collapses, seismic structures, sand liquefaction, and seismic active faults; It is also possible to automatically determine whether the project will affect earthquake monitoring facilities and environment based on the project type.
Wu Tiesheng, a senior engineer, said that the platform made full use of 3D GIS and Internet GIS technology to realize the electronic, standardized and networked management of seismic fortification requirements supervision, which is helpful to improve the level of seismic fortification supervision of construction projects.
Specifically, the platform has improved the technical capability and approval efficiency for determining seismic fortification requirements in Hainan, enhanced the scientific and standardized nature of approval, reduced the time required for approval processes, and lowered government management costs and total project costs. At the same time, it provides a more scientific and reasonable basis for the seismic fortification requirements of construction projects, improves the scientificity of seismic fortification in site selection and design stages, and avoids investment waste caused by improper site selection or unreasonable design. This technology support platform can also be widely used in urban planning, engineering construction, urban disaster prevention management and other aspects, and provide strong support for earthquake prevention and disaster reduction work for professionals in engineering design, scientific research and teaching; It has also achieved procedural, standardized, and unified supervision of seismic fortification requirements, improved regulatory efficiency, reduced management costs, saved manpower and material resources invested by project construction units in this work, and ensured the implementation and execution of seismic fortification requirements throughout the project construction process in terms of systems. And it can provide timely and effective testing services to avoid errors and rework related to seismic fortification of the project, as well as the economic risks arising from it. In addition, on-site supervision of ongoing projects and seismic fortification testing capabilities for completed projects have been established, which can ensure that engineering construction truly has the ability to resist earthquake disasters, improve the ability of the whole society to resist earthquake disasters, and provide strong technical support for creating a safe, harmonious, and earthquake resistant home.
On August 29-30, 2013, the Hainan Provincial Seismological Bureau held a two-day "Training Course on the Application of the Whole Process Supervision Technology System for Seismic Fortification Requirements in the Province" in Haikou City. A total of 56 people, including administrative approval service window managers from 18 cities and counties in the province and the Yangpu earthquake prevention and disaster reduction competent department, as well as specific operators of the whole process supervision technology system for seismic fortification requirements, participated in the training. This training ensured the normal application of the system and improved its usage and service functions. At present, 18 cities and counties in Hainan Province are gradually promoting the use of the "Seismic Fortification Requirements Full Process Supervision Technical Service System" to strengthen the full process supervision of seismic fortification requirements for construction projects in various regions.
Life safety is of great importance, and we can use technological power to reduce human tragedies and improve people's happiness. Technology will also lead us further.
