| 摘 要： | 加纳特码新集装箱码头后轨道梁基础采用钢管桩结构,设计桩端土层为强风化片麻岩。本文首先详细地介绍了本项目的工程地质特点和锤型选择过程,通过理论公式和试沉桩确定了以贯入度控制的停锤标准,进一步用高应变动力检测试验和静载荷试验进行复核并对ENR公式进行修正,为今后类似土层沉桩施工提供一定参考。

| Abstract: | Steel pipe pile structure is used as rear track beam foundation of Tema container terminal in Ghana. The soil layer at the design pile tip is highly weathered gneiss. An introduction to the geological properties and hammer selection is made in detail firstly, and then the hammering criteria controlled with penetration depth is determined through theoretical formula and trial piling, which shall be further verified through high-strain dynamic test and static load test to modify ENR formula. The above research results will provide a reference for driving piles into similar soil layer in the future. |
