The Shallow Ground Temperature Suitability Zoning And Resource Assessment In Chongqing Area

Shallow ground temperature to its economic and energy saving, sustainable development and utilization, and environmental benefit is remarkable advantages, such as making it a nationwide can caused shallow geothermal development boom, the orderly popularization and application, the technology for the guide of shallow geothermal energy development and utilization of and practical guide of the project is very necessary. In order to avoid improper exploitation resources waste, the survey and evaluation of shallow ground temperature can be extremely important.This article fully collect and organize large districts and counties of chongqing before meteorological, geological, hydrological and shallow geothermal exploitation and utilization results, find out work in lithologic structure, hydrogeological condition and the geotechnical layer analysis area testing and field ground temperature test in geotechnical engineering test results, through sorting area rock and soil body heat physical property parameters, physical parameters, characteristics and regularity of ground temperature field distribution, the MAPGIS software of big chongqing, wanzhou district, FuLingOu, qianjiang and processing geological map of one hour economic circle, the meshing and add a grid point. Respectively use traditional division method and the dimensionless method of MAPGIS software for big chongqing, wanzhou district, FuLingOu, qianjiang, and one hour economic circle preliminarily partition, partition results comparing the two methods analysis, found the problem, combined with expert advice later perfect figure processing results. Respectively, the figure can districts and counties of shallow ground temperature suitability zoning maps. Finally according to the results of shallow layer ground temperature can partition diagram and test data, combined with Mapgis software, AutoCAD, etc for each area can make use of shallow geothermal resources, buried tube heat exchange power, degree of soil source heat pump heat balance calculation and analysis.This paper for the first time for large areas and some of the districts and counties of chongqing can shallow ground temperature suitability zoning and resource evaluation, use traditional method and the dimensionless method, two methods for shallow ground temperature can work area suitability zoning and combined with expert advice on drawing is perfect, for the first time on the chongqing area within the scope of the shallow ground temperature can geological, caused by the development and utilization of the environmental impact. In chongqing area of the development and utilization of shallow geothermal can has important reference value.This article is in view of the characteristic of the geological, hydrological conditions in chongqing area, provide the basis for chongqing can of geothermal exploitation and utilization, and also provides a security management policy, has important scientific significance.
