摘要
本文以张家口市崇礼区为研究区,充分利用以往资料,分析地层结构、水文地质条件、岩土体热物性特征和浅层地温场特征,大致查明研究区浅层地温能赋存条件。研究发现,研究区内主要岩性为变质岩和侵入岩,第四系分布范围及厚度较小,各岩石的热导率为1.68~5.27 W/(m·K),比热容为0.7095~0.8837 kJ/(kg·K);地下水主要分布在河谷第四系和沟谷底部的风化带中,地下水水化学类型以HCO_(3)-Ca为主;地温场的有利区分布在尚义-平泉深大断裂及其次级断裂附近。推荐采用高效换热地源热泵系统,为崇礼区的制冷和供暖提供能源。
Taking Chongli District of Zhangjiakou City as the study area,this paper fully utilizes previous data to analyze the geological structure,hydrogeological conditions,thermal properties of rock and soil,and shallow geothermal field characteristics,roughly identifying the conditions for the occurrence of shallow geothermal energy in the research area.Research has found that the main rock types in the study area are metamorphic and intrusive rocks,with a relatively small distribution range and thickness of the Quaternary system,and the thermal conductivity of each rock is 1.68~5.27 W/(m·K),and the specific heat capacity is 0.7095~0.8837 kJ/(kg·K);groundwater is mainly distributed in the Quaternary system of river valleys and the weathering zone at the bottom of valleys,with HCO_(3)-Ca being the main hydrochemical type of groundwater;the favorable areas of geothermal field are distributed near the Shangyi-Pingquan deep fault and its secondary faults.It is recommended to use an efficient heat exchange ground-source heat pump system to provide energy for cooling and heating in Chongli District.
