Rock-soil thermal response test for Mianyang Cigarette Factory

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.
