【摘要】 结合某综合管廊下穿高速公路工程实例，介绍了暗挖法在该工程中的应用和穿越重大风险源时的设计理念，基于有限元分析选用了初支联立二衬独立的暗挖断面方案并顺利完成了穿越段的施工，结合施工监测数据分析了模拟数值与理论数值存在差异的原因，为今后类似工程提供了参考。更多还原

【Abstract】 Combined with a utility tunnel project crossing the expressway, the application of mining method and the design concept of crossing major risk sources are introduced in this paper. Based on finite element analysis, the underground excavation section scheme of simultaneous initial support and independent two lines is selected and the under-crossing is successfully completed. Combined with the construction monitoring data, the difference between simulation value and theoretical ones is analyzed, which can provide reference for similar projects in future.更多还原
