摘要:
为降低油气田区隧道施工风险，以龙泉山隧道为依托，采用数值模拟方法对隧道开挖掌子面前方围岩安全厚度进行分析，并结合现场监测数据对所得结论进行验证。研究结果表明：隧道施工使隧址区围岩应力重分布，且应力变化与围岩距掌子面距离L有关，当L≤0.75D（D为隧道净高）时，围岩处于应力释放区；当0.75D
Abstract:
In order to reduce the risk of tunnel construction in the oil and gas fields,based on the Longquanshan tunnel,the safety thickness of surrounding rock in front of the tunnel face was analyzed by using the numerical simulation method,and the results were verified by the field test data.The results showed that the tunnel construction caused the redistribution of the stress of surrounding rock in the tunnel area,and the stress change was related to the distance L of the surrounding rock from the face.In the range of L≤0.75D (hole diameter),the surrounding rock lay in the stress release zone.When 0.75D
