摘　　要：菲律宾八打雁港板桩码头前墙桩由大直径CT锁口钢管桩组成,该类桩型安装精度是进行前墙施工的关键。结合打桩船施工大直径CT式锁口钢管桩的实例,阐述了大直径CT锁口钢管桩施工精度控制分析与具体方法。该沉桩施工方法效果好,工效高,对类似桩基工程具有重要的参考价值。The front sheet pile walls of quay in Batangas Port of Philippines are made of CT lock steel pipe piles. The installation accuracy of piles is the key to the success of front wall construction. Combining with the example of large-diameter CT lock pipes constructed by using the piling ship, we expounds the construction precision control analysis and concrete method of large diameter CT lock steel pipe piles. The pile construction method has good effect and high efficiency, which has important reference value for similar pile foundation engineering in the future.
