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...

A novel clustering classification method of surrounding rock mass for TBM tunnel
Abstract: Accurate classification of surrounding rock mass can identify the geological conditions in front of the tunnel face in time, and effectively guide the optimization of TBM tunneling parameters and the design of support schemes. According to on-site tunneling data from the 3rd TBM section of Songhua River water supply project in Jilin province, this paper first extracts the rock mass excavability...
