摘要
岩土热响应试验的目的是确定岩土热物性参数。本文提出一种获得更为准确的岩土热物性参数及钻孔内热阻的方法,介绍如何利用岩土热响应试验数据来推导不同工况下(不同埋管形式、加热功率等)地埋管换热器的运行情况,以期为工程设计提供更多翔实的参考数据。
The purpose of geotechnical thermal response test is to get the parameters of the geotechnical thermal properties. Proposes one method through which the borehole re- sistance and parameters of the geotechnical thermal properties can be accurately measured and calculated respectively. Introduces how to use the test data to predict the operation status of vertical ground heat exchanger under the different cases（different ground heat exchanger forms,heating power, etc. ）. Hopes to provide more accurate reference data for engineering design.
