摘要
针对隧洞开挖和支护模拟时灌浆压力的施加难度,采用ANSYS有限元法对潘口导流洞三种不同的施加灌浆压力方案进行模拟计算,获得了隧洞在开挖支护并承受灌浆压力后的位移场和应力场分布规律。通过对比分析认为方案3较合理,为隧洞灌浆压力的施加提供了参考。
Aiming at the difficulty of applying method of grouting pressure for tunnel excavation and supporting simulation, three different schemes of grouting pressure for Pankou diversion tunnel are simulated using ANSYS finite element method. The distribution rules of displacement field and stress field are obtained when the tunnel is excavated, supported and subjected to the grouting pressure. Scheme three is regarded as reasonable by comparing and analyzing the results. Thus, it provides reference for applying methods of tunnel grouting pressure.
