沈阳市典型岩土体组合热响应试验及结果分析

岩土热物性参数是地层热响应特征的直接表征，也是地埋管地源热泵系统设计主要影响因素.热响应试验是获取岩土热物性参数的重要手段之一.针对沈阳市不同地貌单元，选择3种典型岩土体组合地段开展5组热响应试验，综合研究分析了沈阳市典型岩土体组合的综合热响应特征，包括地层初始温度、地层综合导热系数及地层的地温恢复时间，提出了沈阳市西部地区可优先发展地埋管地源热泵系统.这些结果将为沈阳市地埋管地源热泵系统的规划部署及工程的开发利用提供借鉴.

THERMAL RESPONSE TEST AND RESULT ANALYSIS OF TYPICAL GEOTECHNICAL COMBINATIONS OF SHENYANG CITY

Geotechnical thermal parameters, which directly represent the formation thermal response characteristics, are major factors influencing the design of ground source heat pump system. The thermal response test is one of the important means to obtain the parameters. According to the different geomorphic units in Shenyang City, 5 groups of thermal response tests are carried out for 3 typical geotechnical combinations to analyze the comprehensive thermal response characteristics as initial temperature, complex thermal conductivity and ground temperature recovery time of formation. It is suggested that ground source heat pump should be developed first in the western region of the city. The above results will provide references for the planning and utilization of ground-source heat pump system in Shenyang.
