钻孔灌注桩咬合水泥搅拌桩围护结构的浅析

Tentative discussion on retaining structure of cast-in-place bored pile locking cement mixing pile

以南京某地铁区间隧道工程为背景,对钻孔灌注桩咬合水泥搅拌桩围护结构进行了研究,分析了围护机理,具体阐述了咬合桩围护结构设计,指出该围护结构设计方便,施工速度快,成本低,值得推广。

Taking a subway section tunnel project in Nanjing as a background,it does a research on retaining structure of cast-in-place bored pile locking cement mixing pile,analyzes the retaining mechanism,specifically illustrates the retaining structure design of bore locked pile,and points out that the retaining structure design of bore locked pile is worth promoting with the advantages of convenient design,fast construction speed and low cost.
