摘要
结合南京城西干道清凉门隧道明挖施工采用的一种新的基坑支护结构形式——咬合桩,介绍了咬合桩工艺原理,对比分析了类似复杂地质条件下传统基坑支护方式的不足及采用咬合桩的必要性,最后通过实践总结该方案的施工经验,以供类似工程中推广应用。
Combining with the new foundation support structure-biting pile used in Qingliangmen tunnel open excavation of Nanjing west highway,the paper introduces the technical principles of biting pile,compares it with traditional foundation support method under similar complicated geological conditions,analyzes the necessity of applying biting pile,and summarizes its construction experience,with a view to promote its application in similar engineering.
