摘要
通过对肥城市城市规划区浅层地温能赋存条件的研究,结合岩土样、水质分析样等测试数据,利用定性、半定量相结合的层次分析法(AHP),选取第四系厚度、含水层厚度、分层水质状况、地下水水位埋深、钻探施工难度、城市覆盖率、岩溶发育程度、平均热导率、平均比热容、地温等10个要素赋值,建立了地埋管地源热泵适宜性结构模型。研究区地埋管地源热泵适宜性划分为适宜性中等区和适宜性差区,除龙山公园/白云山公园一带为适宜性差区,其他区域均为适宜性中等区。浅层地温能开发利用资源潜力评价及经济效益分析结果表明:研究区200m以浅的浅层地温能容量28.5266×10^(12)kJ/℃;地埋管地源热泵可利用换热功率为25.50×10^(5)kW,夏季可制冷面积为2237.143万m^(2),冬季可供暖面积为1789.091万m^(2)。肥城市城市规划区浅层地温能开发利用潜力大,可带来巨大的经济效益。
Based on the research on the occurrence conditions of shallow geothermal energy in urban planning area of Feicheng City,combined with the test data of geotechnical samples and water quality analysis samples,and using the qualitative and semi quantitative analytic hierarchy process(AHP),the thickness of quaternary system,aquifer thickness,layered water quality,groundwater level,drilling difficulty,urban coverage,karst development degree,average thermal conductivity,average specific heat,groundwater quality were selected to be assigned to values.The suitability structure model of ground source heat pump was established.The suitability of ground source heat pump in the study area is divided into medium suitability area and poor suitability area.Mountain Baiyun Park and Longshan Park is poor suitability areas,other areas are medium suitability areas.The results of resource potential evaluation and economic benefit analysis of shallow geothermal energy development and utilization show that the shallow geothermal energy capacity of the study area is 28.5266×10^(12)kJ/℃.The available heat exchange power of the ground source heat pump is 25.50×10^(5)kW,the cooling area in summer is 2237.143×10^(4)m^(2),and the heating area in winter is 1789.091×10^(4)m^(2).The shallow geothermal energy in the study area has great potential for development and utilization,which can bring huge economic benefits.
