A Case Study on Construction Technology of Large Section Horseshoe-Shaped EPB-TBM Tunnel
Abstract: Previously, mining method is usually used to construct mountain tunnel in loess strata, and shield method has no precedent. Baicheng tunnel of Menghua railway is a mountain tunnel located in loess area. Through contrastive analysis, the proposal of using a large section horseshoe-shaped EPB-TBM with multi-cutterhead to construct Baicheng tunnel was adopted. Afterwards, the TBM was developed by...

Evaluation of Structural Performance and Optimizing Design for Lattice Girders Reinforced Shotcrete
Abstract: Lattice girders have been widely used as a temporary support or part of the permanent lining for NATM tunneling. In order to evaluate the structural performance of lattice girders reinforced shotcrete, influential factors such as diameter of main steel bar and diagonal bar, welding length, stirrup were studied. Moreover, interaction between rock and lattice girders reinforced shotcrete was also...
