研究结论:针对天平山隧道的软岩变形问题，勘察阶段已经有了较为充分的认识，并为此开展了综合勘探，从岩性、构造、地应力等方面对隧道开挖所经受的变形范围及程度进行了详细的分析。从目前开挖情况看，2号斜井及相应正洞穿过下朝塘断裂带变形预测较为合理，而页岩为主夹炭质页岩段的变形预测还有待开挖对比。

Research conclusions: For the soft rock deformation of the Tianpingshan Tunnel，the comprehensive survey was conducted and the analysis of the deformation range and deformation level caused by the excavation was made from the lithology characters， structure and ground stress． It can be seen from the current excavation that the prediction of the deformation of the the incline shaft 2 and the main tunnel that under － passes the Chaotang Fault Zone is rather reasonable and whether the prediction of the deformation of carbonaceous shale area is correct or not，it needs waiting for comparing it with the excavation result．
