本文旨在以苏州地铁一号线近接盾构隧道施工为背景,通过Midas-GTS有限元软件对盾构隧道近接施工进行二维数值模拟,分析近接隧道施工对既有隧道管片受力的影响。
The purpose of this paper is to establish a two-dimensional numerical simulation of proximity tunneling of shield tunnel with Midas-GTS finite element software based on the construction of shield tunnel near Suzhou Metro Line 1, and to analyze the effect of proximity tunnel construction on the stress of existing tunnel segments .
