Test time optimization of thermal response under bedrock geological conditions
摘要：
重点分析了基岩地质条件下测试持续时间对岩土导热系数测试结果的影响。根据对实测数据的分析，分别获取了该地质条件下单U和双U工况下适宜的测试持续时间及舍弃的初始小时数。测试持续时间分别宜达到60 h和50 h，舍弃的初始小时数分别不宜超过20 h和10 h。此外，通过CFD软件模拟的方式，分析了测试环境对长时间热响应测试结果的影响。

Abstract：
Presents the influence of the test time on the soil thermal conductivity under bedrock geological conditions. According to the analysis of the measured data, obtains the optimal test duration of 60 h and 50 h and the abandoned initial hours of less than 20 h and 10 h for single Utype and double Utype conditions, respectively. In addition, according to the CFD software simulation, analyses the influence of test environment on long time thermal response test result.
