大直径嵌岩桩嵌岩深度计算

Calculation of large diameter rock-socketed pile rock-socketed depth

目前,大直径嵌岩桩嵌岩深度计算结果偏差较大。针对此问题,以鼠浪湖矿石中转码头大直径嵌岩桩现场水平力试验结果为基础,对比各种公式计算出的结果。得出目前采用的几种方法计算出的嵌岩深度偏差较大,而张有龄法计算出的嵌岩深度比较符合实际情况的结论。推荐采用张有龄法计算大直径嵌岩桩的嵌岩深度,并给出计算公式。

At present, the calculation results of large diameter rock-socketed pile rock-socketed depth are deviated greatly.Based on the test results of large diameter rock-socketed pile in Shulanghu mine transfer wharf, the results are compared with the various formulas.It is concluded that the embedded depth of rock-socketed depth is relatively large, and the rock-socketed depth calculated by ZHANG You-ling method is in accord with the actual situation.It is recommended to calculate large diameter rock-socketed pile rock-socketed depth by Zhang You-ling method and give the calculation formula.
