摘要 本文结合市政管道软弱深基坑的施工实例，阐述了基坑围护方案的比选过程 钢板桩围护的承载能力的检算及确保钢板桩
： 、
围护结构各工序施工质量的技术措施。确保了基坑安全，加快了施工进度，也取得了良好的经济效果。
Abstract: Combining the construction example of weak and deep foundation pit of municipal pipeline, this paper expounds the
comparison and selection process of foundation pit enclosure scheme, the checking and calculation of the bearing capacity of the steel sheet
pile enclosure and the technical measures to ensure the construction quality of each process of the steel sheet pile enclosure structure. It
ensures the safety of the foundation pit, speeds up the construction progress, and also achieves good economic results.
