摘　　要：根据实际工程项目,从地质条件、建筑结构和地埋管布置形式等方面对建筑筏板基础下地源热泵应用特性进行总结,建筑筏板基础下地源热泵系统实施前应着重考虑工程地质条件,在卵石或砂土地层可增加泥浆稠度,提高钻孔的自稳性;在地下水丰富地区需测算地下水水位或承压水头,必要时采取有效水位控制措施;地源热泵系统实施时应与建筑下返结构、建筑桩基持有一定安全距离,加强水平沟回填质量管控,减小地基扰动;同时根据基坑支护形式、检查井位置,合理选择地埋管布置形式,优先选用少焊点地埋管连接方式,提高施工质量,降低焊点渗漏风险。Based on actual engineering projects,this paper summarizes the application characteristics of ground source heat pumps under building raft foundations from aspects such as geological conditions,building structure,and buried pipe layout.before implementing the ground source heat pump system under building raft foundations,special consideration should be given to engineering geological conditions.in pebble or sandy soil layers,the consistency of the slurry can be increased to improve the self-stability of the borehole;in areas with abundant groundwater,it is necessary to measure the groundwater level or artesian head and take effective water level control measures if necessary.when implementing the ground source heat pump system,a certain safe distance should be maintained from the building's substructure and pile foundation,and the quality control of horizontal trench backfilling should be strengthened to reduce foundation disturbance.at the same time,according to the form of foundation pit support and the location of inspection wells,the layout form of buried pipes should be reasonably selected,and the connection method of buried pipes with fewer welding points should be preferred to improve construction quality and reduce the risk of welding point leakage.Compared with conventional systems.
