黄浦江大桥正桥桥墩基础采用外径1212mm的大型钢管桩,桩长约50 m(经试验后实际采用46.0m),拟靠水冲打入粉砂层约18～20m。为探讨合理的打桩工艺以及取得有关桩基设计的基本依据(如极限承载力、土层摩阻力、极端土反力等),特进行了钢管桩的垂直静载试验。在分析试验资料时,除了直接提供生产设计所需要的数据外,还作了进一步的 The foundation of the bridge pier of the Huangpu River Bridge is a large steel pipe pile with an outer diameter of 1212mm. The length of the pile is about 50m (actually 46.0m after the test), and is about 18-20m of silt layer. In order to explore the reasonable piling technology and obtain the basic basis of pile foundation design (such as ultimate bearing capacity, soil resistance, extreme earth reaction, etc.), the vertical static load test of steel pipe piles was carried out. In the analysis of test data, in addition to directly provide the data required for production design, but also made a further
