【摘要】 为了验证单桩承载能力,了解桩周和桩端阻力,采用钻孔灌注端承桩进行荷载和应变测试,并采用循环荷载方法,进行了端承桩荷载传递与阻力分析试验。根据静载试验和阻力测试结果,并依据地层剖面,分别求得单桩容许承载力、轴向力的分布、桩周岩土阻力和桩端岩基阻力,同时对如何考虑桩周阻力和利用桩端地基强度,提出了建议。更多还原

【Abstract】 In order to proof bearing capacity of single pile and find out friction resistance around pile and pile base resistance,the load transfer and resistance analysis test of end-bearing pile are taken by using the load and strain test of drilling hole perfusion end-bearing pile and the cyclic loading method.According to the results of static load experiment and resistance test and the stratum section,the single pile allowable bearing capacity,the distribution of axial force,soil resistance around pile and pile base resistance are calculated.At the same time,some opinions about how to consider friction resistance around pile and use pile base strength are suggested.更多还原
