大伙房水库输水工程隧洞结构应力仿真分析

Simulation-based analysis on stress of tunnel structure for water conveyance project of Dahuofang Reservoir

应用有限元法对辽宁省大伙房水库输水工程主体隧洞结构进行了仿真分析,从而得到隧洞结构的应力分布规律,研究确定薄弱部位并采取相应的稳定措施,以便保证隧洞施工的安全与经济。

Based on the main tunnel for the water conveyance project of Dahuofang Reservoir in Liaoning Province, a simulationbased analysis is made on the tunnel structure with the finite element method （FEM） ; in which the stress＇distribution law of the tunnel structure is analyzed and the weak locations concerned are studied, so as to strengthen the stability measures and guarantee the safe and economic construction of the tunneling.
