传递函数法计算嵌岩桩承载力

Numerical Calculation of Bearing Capacity of Rock-socketed Piles Cast-in-place with Load Transfer Method

从研究嵌岩桩的荷载传递性能开始，由实测资料分析得出桩的荷载传递函数，再用位移协调法对８根试桩进行计算，结果与试桩资料吻合．并研究了嵌岩深度。

This paper begins with the study of the characteristics of the load transfer of the rock-socketed pile cast-in-place. The load transfer function can be obtained from the analysis of the data measured in-situ. 8 piles cast-in-place in Fujian Province are calculated with the method of equal pile point settlement. The result of the calculation is in agreement with the data of the tested piles. The influences of the pile with various rock-socketed lengths, length-diameter ratios and depths of sediment on the axial bearing capacity of the pile are discussed respectively.
