Study on Semi-dark Tunneling Method for Connected Tunnel

建立复杂地质体的三维精细结构模型是地质体稳定性数值模拟分析的前提,也是进行滑坡体三维数值精细分析的关键技术问题。文章根据半坞隧道地质勘探资料及结构设计资料,建立了边仰坡滑体的三维地质结构模型,并结合各个施工阶段的位移、剪应力、剪应变、边坡稳定性系数等指标,对比分析了两种不同的施工工序,推荐了相对安全的信息化施工方案。

The establishment of three-dimensional fine structure model for complex geologic bodies is the premise for the numerical simulation analysis of geologic body stability,and it is also a key technical problem for the detailed three-dimensional numerical analysis of landslide bodies.Based on geological exploration data and structural design data of Banwu Tunnel,this article established a three-dimensional geological structure model of slope landslide body,then,combining the displacement,shear stress,shear strain,slope stability coefficient,and other indicators in each construction stage,it compared and analyzed two different construction processes,and recommended a relatively safe information construction program.
