摘　　要：以广州地铁6号线东湖车站为背景,研究在施工时,上台阶开挖过程中需把中部临时中隔壁拆除8 m后对周围土体和结构产生的影响。本次数值模拟主要检验拆除8 m临时中隔壁时对结构的安全性和地表沉降的影响。Based on building the Donghu subway station of 6th Line in Guangzhou, tile present article states that the middle wall of 8 meters long should be taken apart in the course of digging top bar and studies its influence on the surrounding soil and structure. This numerical value imitation aims at examine the influence of the middle wall on the earth＇s surface settlement when it is taken apart for 8 meters long.
