摘要
本文结合某水电站勘探平硐的地质及地温实测资料，在考虑地形、岩性、构造及地下水活动等因素的基础上，用有限元反演的方法，对山体的地温场进行了数值模拟，并对进一步掘进时隧洞的地温场变化作了预测。
In this paper the geotemperature field of a mountain related to excava-tion of a deeply buried long tunnel is simulated numerically with FEM back-deduc-tion method，based on the measured temperature changes of the tunnel section exca-vatedIt is noted that the complicated geological structure and activity of ground water are considered with reasonable adjustment of boundary conditions during the simulation. According to the results，the geotemperature of the tunnel section to be excavated is forcasted.
