摘　　要：土壤初始温度是土壤源热泵系统设计及运行的重要参数.依据测量土壤初始温度分布的方法进行试验,根据试验数据把土壤分成3层,分别采用算术平均法、加权平均法、积分平均法3种数学处理方法得到土壤初始平均温度.试验结果表明仅选择深度在10m及以下测点时,3种数学处理方法计算得到的土壤初始平均温度基本相同,但算术平均法最为简便,因此,工程上建议使用算术平均法计算土壤初始平均温度.The initial temperature of the ground has an important influence on the efficiency of the ground-source heat pump system. A method to measure the initial temperature profile of the ground is introduced. The ground was divided into three layers according to the experimental data. Three mathematical methods were used to get the initial average temperature of the ground, including arithmetic average method, weighted average method, and integral average method. The experiment results show that the initial average temperature of the ground getting by three mathematical treatment under 10 meters or deeper has the same stability. The arithmetic average method is the most simple method, so it is recommended for engineering application.
