基于埋深及围岩等级的暗挖工程施工围岩时空效应研究

摘要

The ducoment takes the mined underground metro station of Qingdao subway project as the background, and expounds the deformation law and time-space effect of surrounding rock in a particular geological conditions of soil and rock composition stratum during the construction process of the shallow underground excavation station based on the buried depth and surrounding rock level.%本文以青岛地铁一期工程暗挖车站为背景,阐述了土岩结合地层下,浅埋暗挖工程在施工过程中基于埋深及围岩等级,围岩的变形规律及时空效应.
