摘要/Abstract

摘要： 笔者介绍了一大型钻孔灌注桩静载荷试验及桩身应力测试,并根据测试结果,重点分析了粘性土层中摩擦型灌注桩的承载力变形特征,并对桩侧极限摩阻力及桩端承载力的取值问题进行了讨论.本文得出的结论对今后大型钻孔灌注桩的设计及规范的修订具有参考价值

关键词: 摩擦型钻孔灌注桩, 单桩承载力, 单桩静载荷试验

Abstract: The static load test for the large bored pile and the measurement of the pile shaft stress were presented in this paper.The behaviour of the friction-bored pile's capacity-settlement was analysed emphatically,and the ultimate values of the pile shaft friction resistance and the ultimate tip resistance were discussed thoroughly.The documentation gives guidance for future research and development of codes for large bored pile.

Key words: friction-bored pile, pile capacity, pile static loading test
