摘要
基于西施坡隧道,按照隧道开挖与支护顺序,分析监测数据,采用FLAC3D软件对隧道开挖与支护全过程进行数值模拟。分析结果表明,数值模拟与信息化施工监测数据吻合较好,其土体计算参数选择合理,数值模拟方法正确,为类似隧道工程的变形预测及设计提供参考据。
Based on the Xi Shi Po tunnel, according to the tunnel excavation and supporting sequence, analysis of monitoring data, using FLAC3D numerical simulation of tunnel excavation and supporting process. Analysis results show that the numerical simulation are in good agreement with informatization construction monitoring data, the selection of soil parameter is reasonable, the numerical simulation method is correct, for the deformation forecast of the similar tunnel engineering and providing reference for design.
