【摘要】 通过在热响应试验孔内埋设温度传感器,并且在孔内的PE管上部40 m深度范围内逐点下放测温探头的机动测温,对42眼地埋管热响应试验孔进行每月一次,为期1 a的长期监测。初步查明杭州市平原区100 m深度范围内岩土初始平均温度为19.21²2.49℃;恒温层厚度范围为9²1 m,温度范围为18.2²0.0℃;地温梯度范围为1.22×10^-23.85×10^-2℃/m。平原区浅部大地热流值范围为30.10⁷5.02 m W/m²。并研究地温场与地质构造之间的关系等。为杭州市开展浅层地温能资源评价、地源热泵系统设计提供重要的基础参数。更多还原

【Abstract】 Original ground temperature distribution, the initial average temperature, geothermal gradient andgeothermal heat flux and other parameters of the geothermal field are basic parameters when carried shallow geothermalenergy resource assessment,ground source heat pump system design. Geotemperature had been monitored for once amonth in one year in forty-two thermal response boreholes（TRB）by buried temperature sensors along the lower part ofthe boreholes and by insert temperature sensor into the PE pipe gradually along the up part of the borehole. Preliminarycharacteristic parameters of geotemperature field in Hanzhou are as follows:the initial average ground temperature is19.21-22.49 ℃,zone of constant temperature is 9-21 m in thickness with temperature of 18.2-20 ℃,the geothermalgradient is in the range of（1.22-3.85）×10^-2℃/m,geothermal heat flux in plane area is in the ranging of 30.10-75.02 mW/m². The relationship between the geothermal field and geological structure has also been studied in this paper.更多还原
