摘　　要：地下水地源热泵系统优点突出,但由于系统运行过程中对地下水的水位、水温、水质有一定的影响,因此,地下水地源热泵系统开发利用对工程场地地质环境影响的研究十分必要。选取关中地区某学校地下水地源热泵系统工程及陕南地区某小区售楼部地下水地源热泵系统工程,通过监测工程运行期间地下水温度、水位和水质动态数据,分析地下水地源热泵系统开发利用过程中对地质条件的影响。结果显示:当工程采灌平衡时,地下水位恢复迅速,地下水地源热泵工程长期运行不会对区域地下水位产生明显的改变;在一个完整的供暖、制冷年内地下水回灌井从井口至井底不同深度地下水温度均处于平衡状态;工程运行过程中水质常规阴阳离子、总硬度、总碱度、总溶解性固体、pH值和水化学类型没有明显的改变,有毒物质中的氰化物、汞离子、砷离子、铅离子、铬离子、挥发酚、铜离子一直处于检出限以下,仅有锌离子浓度受工程运行有一定变化。论文通过分析地下水地源热泵系统开发利用对工程场地地质条件影响,为地下水地源热泵系统的科学推广应用提供技术支撑。Groundwater ground source heat pump system has outstanding advantages,but the system operation process has certain influence on groundwater water level,water temperature and water quality.So it is necessary to study the impact of the development and utilization of groundwater ground source heat pump system on the geological environment of the project site.In this paper,a groundwater ground source heat pump system engineering in a school of Guanzhong area and a groundwater ground source heat pump system engineering in a sales department of Southern Shaanxi area were selected for studying.The authors analysised the influence on geological conditions by monitoring the groundwater temperature,water level and water quality dynamic data during the operation of the project.The results show that the groundwater level recovers rapidly when the project is balanced,and the long-term operation of the ground source heat pump project will not change the regional water table significantly.In a complete heating and cooling year,the groundwater temperature at different depths of the well is in equilibrium.In the running process,water quality including cation and anion,total hardness,total alkalinity,total dissolved solids,pH value and hydrochemistry type had no obvious change.Cyanide,arsenic,mercury ions of toxic elements,volatile phenol,lead ions,chromium ions,copper ions were below the detection limit.Only zinc ions concentration operation was changed by engineering.This paper provides technical support for scientific popularizing and application of the groundwater ground source heat pump system,by analyzing the influence on geological conditions of engineering site caused by the development and utilization of groundwater ground source heat pump system.
