摘要
城市化带来的交通堵塞问题日益严峻。对于地铁隧道而言,邻近建筑物对其安全性有着不可忽视的影响。因此如何准确预测深基坑对现有地铁隧道的影响是亟待解决的问题。本文结合某工程实例,采用有限元软件对基坑进行三维建模处理。并据此对地铁隧道与基坑开挖之间的关系进行分析研究,并通过对比仿真结果与实测值的方式得出结论。
The traffic jam caused by urbanization is becoming more and more serious.For subway tunnel,the safety of adjacent buildings cannot be ignored.Therefore,how to accurately predict the influence of deep foundation pit on existing subway tunnels is an urgent problem to be solved.In this paper,finite element software is used to model the foundation pit.Based on this,the relationship between subway tunnel and foundation pit excavation is analyzed and studied,and a conclusion is drawn by comparing the simulation results with the measured values.
