摘要
基于乌鲁木齐砂卵石地层地铁隧道现场监测数据,采用回归分析方法对典型断面地表沉降进行分析,得到适用于砂卵石地层的Peck公式,并进行了现场数据验证.研究成果表明得到的peck公式能够有效预测砂卵石地层盾构施工地表沉降,具有工程指导意义.
By using the regression analysis method,the monitoring data from the subway tunnel project through cobble stratum in Urumqi were analyzed and an applicable Peck formula was derived which was validated by field data.The research result indicates that the Peck Formula can successfully predict ground subsidence of cobble stratum and is of practical significance.
