柬埔寨优联码头钢管桩变形处理

建造在风化岩地基上的高桩码头，当地质变化较大、岩层起浮波动且存在较多裂隙或地质与设计不符时，若岩石强度高，钢管桩在打设过程中容易发生变形，导致嵌岩桩冲孔过程中发生卡锤，无法正常成孔，影响桩基施工。以柬埔寨优联码头工程为例，阐述如何避免嵌岩桩施工时钢管桩的变形，介绍钢管桩变形后采用水下切割并对切割处进行堵漏等方法，保证了嵌岩桩后续的正常施工。施工完成的嵌岩桩经检测均为I类桩，证明此方法的实用性和可操作性。

Deformation of steel pipe piles in Cambodia Union Port

The high-pile wharf built on weathered rock often encounters large changes in local quality,fluctuations in rock formation and with many cracks,or geological and design inconsistency.If the rock strength is high,the steel pipe pile is prone to deformation during installation,resulting in embedding.The hammer is generated during punching of the rock-embedding pile,and the hole cannot be formed normally,which affects the construction of the pile foundation.Taking the Cambodia Union Port as an example,We explain how to avoid the deformation of steel pipe piles during construction of rock-socketed piles,introduce the method of underwater cutting and plugging of the cut parts of the steel pipe pile after deformation,which ensures the normal construction of the rock-socketed piles.The completed rock-socketed piles are all tested as Class I piles,which proves the practicability and operability of this method.
