地下水源热泵抽取地下水形成大范围的降水漏斗是否会引起地面及建筑物出现过大沉降一直为业内关注。通过调查沈阳市应用水源热泵技术建筑物的现状,经理论分析、计算和室内试验得出,抽取、回灌地下水引起的地面附加沉降导致的沈阳市砂土地基上建筑物的变形均在规范允许范围内。
Groundwater source heat pump to extract groundwater to form a wide range of precipitation funnel will cause the ground and buildings have been excessive settlement has been the industry’s attention. By investigating the present situation of buildings applying water source heat pump technology in Shenyang, theoretical analysis and calculation and laboratory tests show that the deformation of buildings on the sandy soil foundation in Shenyang City caused by additional ground settlement caused by extraction and recharge of groundwater is within the specifications Range.
