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
The author introduces the static load test and pile stress test of a large cast-in-place bored pile. According to the test results, the deformation characteristics of the bearing capacity of the bored cast-in-place bored pile are analyzed emphatically. Bearing capacity of the problem was discussed.The conclusions drawn in this paper for the future large-scale cast-in-site bored pile design and revision of a reference value
