天津港东突堤北侧集装箱码头PHC管桩打桩应力试验研究

Experiment and Study of Piling Stress of PHC Tubular Piles for Container Terminal on North Side of East Pier in Tianjin Port

天津港地质条件为软土地基,其码头结构基本上采用高桩梁板式的结构形式。为了研究PHC大管桩在本地区的适用性,并为今后大型深水泊位的建设作必要的技术储备,在天津港东突堤北侧集装箱码头连接段进行了该桩型的综合试桩。文章主要介绍打桩应力的测试内容,包括打桩应力的测试方法以及打桩应力测试结果。

Geologically,Tianjin Port sits on soft soils and the wharfs and quays in the port are basically of the structure of piles with beams and slabs.To study the feasibility of using large diameter PHC tubular piles in this region and to prepare necessary technical reserves for construction of deep-water berths in the future,comprehensive tests of this type of piles were made at the connection section of the container terminal on the northern side of East Pier in Tianjin Port.The paper deals mainly with the experiments on the piling stress,including the methods to carry out the experiments on piling stress and the measured results of the experiments.
