通过对章丘区浅层地温能赋存条件的研究,结合现场热响应试验、岩土样品测试等数据,采用层次分析法和指标法对研究区进行了地埋管地源热泵系统开发利用适宜性分区,并概算了浅层地温能资源量、评价了开发利用资源潜力、进行了经济和社会效益分析。结果表明:适宜性区面积76.38km^(2),占研究区面积的95.48%;适宜区内120m以浅浅层地温能热容量21.3228×10^(12)kJ/℃。研究区全部利用地埋管地源热泵系统,夏季可制冷面积5353.1278×10^(4)m^(2),冬季可供暖面积6504.6662×10^(4)m^(2)。浅层地温能开发利用潜力巨大,经济和社会效益明显。

Through study on the occurrence conditions of shallow geothermal energy in Zhangqiu area,combining with the data of field thermal response test and geotechnical sample test,the suitable zoning for the development and utilization of buried tube heat pump system in the study area is carried out by using the principle of analytic hierarchy process and index method.In addition,the amount of shallow geothermal energy resources is estimated,the potential of exploitation and utilization of resources is evaluated,and the economic and social benefits are analyzed.It is showed that the area of the suitable area is 76.38km^(2),accounting for 95.48%of the the study area,and the shallow geothermal energy heat capacity of 120m in the suitable area is 21.3228×10^(12)kJ/℃.The ground source heat pump system with buried pipe is used in all the study area.The refrigeration area is 5353.1278×10^(4)m^(2) in summer and the heating area is 6504.6662×10^(4)m^(2) in winter.Therefore,the development and utilization potential of shallow geothermal energy in Zhangqiu area is huge,and the economic and social benefits are obvious.
