摘要
结合嵌岩人工挖孔桩的工程实践,对嵌岩人工挖孔桩的承载性能进行了研究,通过对试验结果的分析发现,扩底直径的大小对桩的承载性能影响很大,同时,单位端阻呈现出一定的尺寸效应,扩底直径越大,极限单位端阻越小。
Bearing capacity of hand-dug rock-socketed pile were studied combining with engineering. The diameter of enlarged toe have a great influence on the bearing capacity of hand-duged pile. Meanwhile, the unit end resistance showed a certain size effect and the larger is diameter of the enlarged toe, the smaller is the ultimate unit end resistance.
