摘要
Abstract
The tunnel section of shield end from Tianqiao -Yongdingmenwai of Beijing Metro Line 8 is deeply buried and contains water-rich sandy cobble stratum. In order to reduce the risk of gushing water and sandstone when the shield arrives, a soil reinforcement scheme is designed. Firstly, the way to reinforce is determined by comparing different methods; then according to theoretical calculation and experience analogy, the scope of soil reinforcement is obtained;finally, precipitation scheme is presented through theoretical calculation and numerical simulation. The results can provide reference for future design and construction of similar projects.关键词
