Finite Element Analysis of Single Fractured Rock Mass Flow Heat Transfer

在岩体水力学研究中,岩体渗流场与温度场的耦合分析一直是重点问题,而单裂隙水流下的岩体稳定温度场分析对于岩体-水流传热影响很大。文章基于FEPG软件数值仿真模拟裂隙岩体二维稳定温度场的分布,结合具体算例分析裂隙网络非连续介质的渗流场和温度场的相互耦合作用,所得计算成果对温度场影响岩体稳定性的研究具有一定的指导意义。

In rock mass hydraulics research,an important issue is the coupled analysis of the rock mass seepage field and temperature field,however,the analysis for rock mass stability temperature field under single fractured flow impacts greatly the rock mass-flow heat transfer. Based on FEPG software valuable simulation,this study shows the distribution of fractured rock mass two-dimensional stable temperature field, combined with the detailed calculation, to analyze the coupling interaction of fractured net discontinuous-medium seepage field and temperature field,the results calculated are of significant for guiding the research of temperature field to impact the rock mass stability.
