摘要
以北京长安复线隧道浅埋暗挖工程为背景,对目前经常采用的台阶法开挖、小导管超前注浆及喷射砼三种技术措施,采用数值仿真技术,对其控制地表沉降的有效性进行了定量分析,可供设计、施工参考。
Based on the shallow depth exallation of the Beijing Chang＇an Fuxian tunnel, numerical simulation was applied to quantitatively study the effects of controlling ground settlement by means as step excavating, pre- filling slurry by tubes and shotconcrete. Some conclusions are obtained.
