灌注桩钢护筒在高桩码头施工平台中的应用

在高桩码头水上冲孔灌注桩施工过程中，利用灌注桩钢护筒进行水上施工平台搭设，是确保施工质量、工期和安全的关键。文章对直线段和接岸段施工平台进行结构设计，并进行波浪作用下稳定性验算，沉降位移量均满足设计及规范要求，水上施工平台稳定安全，并在施工检测成果中得到验证。

Application of steel casing of cast-in-place pile on high-pile wharf construction platform

During the water cast-in-place piles of high-pile wharf construction, using steel casings of cast-in-place piles to built the construction platform over water, which is the key to ensure the quality, schedule and safety of the construction. This paper makes the structural design of the straight line segment and nearshore segment construction platforms, and carries on the stability checking calculation under the wave action. Both the settlement and displacement meet the design specification requirements, the overwater construction platform is stable and safe, which has been validated in the construction detection achieve- ments.
