绵阳烟厂岩土热响应测试
Rock-soil thermal response test for Mianyang Cigarette Factory
摘要：
设计了既能进行放热试验又能进行吸热试验的岩土热响应测试系统。用VBA语言开发了基于Excel的热响应分析软件。该系统及软件在绵阳烟厂得到成功应用，测试得到了土壤的原始温度、导热系数和体积比热容以及单U形管和双U形管单位孔深吸、放热量等参数，可为工程设计提供依据。

Abstract：
Designs an in situ system for rock-soil thermal response test, by which heat extraction and injection tests can be conducted. Using VBA language, develops a programme based on Excel to calculate rock-soil properties. Applies the system and the programme to Mianyang Cigarette Factory successfully and obtains the parameters of initial temperature, thermal conductivity and volume specific heat of the soil, and the data of heat exchange rate per meter of single U-type borehole and W-type borehole, providing basic data for project designing.
