摘要

摘要: 基于招商银行深圳分行大厦深基坑开挖工程,考虑隧道衬砌与土的相互作用,采用ABAQUS数值模拟研究了基坑开挖对邻近地铁隧道的影响。计算分析结果表明：基坑开挖对邻近地铁盾构区间产生一定影响,但影响程度较小,沉降与位移值均在规范要求范围之内;地表沉降、隧道衬砌位移随基坑开挖深度加深逐渐变大,在内支撑间距离较大时,沉降与位移增加速率较大;考虑衬砌与土的相互作用,隧道的水平位移值明显低于支护桩,基坑开挖对大直径管道影响计算分析中,应考虑管-土的相互作用。

Abstract: Based on the deep excavation of the building of Shenzhen Branch of China Merchants Bank, considering the interaction between soils and tunnel linings, the impact of excavation on the adjacent subway tunnels is studied by using the finite element software ABAQUS. The calculated results indicate that the influence of foundation excavation on the adjacent subway shield zone is small, and the surface settlement and displacement of values linings are in the limited range. The surface settlement and tunnel lining displacement become larger with the deeper excavation, which have a higher growth rate with the larger distance between the inner support. The horizontal displacement of tunnels is significantly lower than that of the retaining piles considering the interaction between soils and linings. Therefore, the pipe-soil interaction should be considered when analyzing the impact of excavation on large-diameter pipes.
