饱和软黄土地铁隧道施工地表沉降分析与预测

摘要

Based on the construction and on-site monitoring of Chaoyangmen-Kangfulu tunnel of Xi' an Subway Line 1 built in saturated soft loess, the paper analyzes the vertical and horizontal development and distribution of ground surface settlements due to the excavation of single-and double-track tunnels, and by using Peck formula the paper establishes a surface subsidence prediction model for single-and double-track subway tunnels excavated in saturated soft loess.%结合西安地铁1号线朝阳门——康复路暗挖区间饱和软黄土地段隧道施工及现场监测,对单线、双线隧道开挖纵向及横向地表沉降发展和分布规律进行分析,运用Peck公式建立饱和软黄土地层地铁隧道单线及双线开挖地面沉降预测模型.
