摘　　要：以广州地铁6号线东湖车站为背景,研究在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,数值模拟主要检验拆除临时中隔壁时对结构的安全性和地表沉降的影响.Taking East Lake Station of Guangzhou Metro Line 6 for example, this paper studies the effect of removing eight-meter temporary middle septa on the stability of surrounding soil and the structure during the bench excavation process. The numerical simulation confirms the influence of removing the temporary middle septa on the structure security and the ground settlement.

关 键 词：地铁车站 中隔壁 数值模拟 地表沉降
