摘要
阐述了在不同条件下嵌岩桩桩端阻力的几种计算方法,将现行的技术规范同其它方法进行比较,得出按现规范计算的值偏小的结论,总结了嵌岩桩载荷试验时典型Q^S曲线特征,指出了Qb与L/d和hr/d之间的关系,并提出了几点提高嵌岩桩桩端阻力的建议。
Several computation methods of ending bearing capacity of rock-socketed pile in different condition are mainly discussed in this paper, the calculated results of ending bearing capacity from code is smaller than others ,which is obtained through comparing the active technical codes with other methods concerning end bearing capacity. This paper sums up the features of the typical Q -S curves and points out the relations among and and ,as well as several advice is proposed to improve the end bearing capacity.
