摘要： 随着地源热泵技术的应用，岩土换热器的设计水平逐渐提高。而真正对岩土换热器性能影响的关键在于岩土导热性，如系统钻孔数量的确定都需以岩土导热系数作为依据，假若钻孔数量不合理，整个系统初期投资的合理性将难以保障，这样地源热泵技术的实际效果也将受到影响。对此，文章将对地源热泵系统与岩土热物性测试的相关概述、测试中验证校核平台与换热器模型的构建以及影响测试准确性的具体因素进行探析。

Abstract: With the application of ground source heat pump technology and the design level of rock and soil heat exchanger gradually improving. Rock and soil thermal conductivity is the key of the influence of the heat exchanger performance, such as the number of drilling must be based on rock and soil coefficient of thermal conductivity;if the quantity is not reasonable drilled, the rationality of the initial investment of the whole system will be difficult to guarantee, so the actual effect of ground source heat pump technology will also be affected. This article explores the ground source heat pump system and related overview of thermal physical test in geotechnical, test validation check platform and model building of the heat exchanger, and analyzes specific factors influencing the accuracy of the test.
