At the press conference of "Guiding Opinions on Strengthening Urban Geological Work" held on September 6, Wang Kun, deputy director of the China Geological Survey, introduced the latest progress of urban geological survey in Xiong'an New District.
In accordance with the requirements of "world vision, international standards, Chinese characteristics, and high-point positioning", the geological survey thinking of Xiongan New Area was clarified, and the idea of "building a world-class and transparent Xiongan, creating a global model for geothermal resource utilization, and building a multi-element urban geological survey demonstration" The base provides four major vision goals for the planning, construction, operation and management of the Xiong’an New District.
In June of this year, the field work of geological survey in Xiongan New Area was officially launched. After more than two months of hard work, the first stage of geological survey work was successful.
The geological survey mainly obtained the following five conclusions:
First, the site stability and engineering construction suitability in the area are generally good, with 89.5% of the site stable and basically stable areas, both of which are suitable or more suitable for engineering construction; second, the key survey areas have superior underground space development and utilization conditions and are suitable for large-scale development The third is that the soil environment in the key survey area is clean, and the clean area accounts for 99.3%; the fourth is that the quality of groundwater is generally good, but the groundwater is still in a state of overexploitation, the groundwater level continues to decline, and the ground subsidence is increasing; the fifth is that the area is suitable for shallow With the development and utilization of geothermal energy, the land area suitable for the development and utilization of geothermal resources in the starting area is about 12 square kilometers, which can meet the heating and cooling needs of about 30 million square meters of building area.
In the next step, we will accurately meet the needs, advance the geological survey work in the Xiongan New Area with a definite goal, and fully serve the planning, construction and management of the Xiongan New Area.
The first is to carry out preliminary surveys of the Rongcheng geothermal field, detailed engineering geological surveys in key areas, deep hydrogeological exploration tests, and deep three-dimensional geological structure detection, and initially establish a transparent Xiongan digital platform framework to provide basic information and decision support for the preparation of controlled detailed planning .
The second is to carry out high-resolution surveys of areas with severe land subsidence, build a three-dimensional monitoring network for land subsidence, establish groundwater simulation and three-dimensional land subsidence models, assess land subsidence risks, and provide decision-making basis for project planning and construction and land subsidence risk prevention and control.
The third is to fully implement the geothermal field survey, conduct in-depth multi-element urban geological surveys, systematically establish a national land resources and geological environment monitoring and early warning network, and fully build a transparent Xiongan digital platform to provide the entire process of geology for the planning, construction, operation and management of the Xiongan New Area solution.
