摘要
随着城市化建设的快速发展,各类深大基坑在许多城市中频繁涌现。围护结构变形量对基坑安全起着决定性作用,而围护结构变形量的影响因素众多,针对基坑设计中布设相对灵活的支撑,在简述弹性地基梁计算方法的基础上,以汕头苏埃隧道南岸明挖段基坑为工程背景,分析了支撑布设对围护结构变形量的影响,为今后类似工程的设计与施工提供参考。
In this paper, on the basis of the theory of elastic foundation beam method, taking the bottom-up excavation foundation pit of Shantou Su＇ai Tunnel as an example, the influence of bracing arrangement in enclosing structure deformation has been analyzed, which could provide references for future design and construction of similar projects.
