群桩性能与单桩性能完全不同.新的计算方法是采用群桩的影响系数,该系数是下面两个系数的乘积:一是桩的相互作用系数Ki,二是桩在桩台处嵌固的约束系数Kr.
The performance of the pile group is completely different from that of a single pile. The new calculation method is to use the impact coefficient of the pile group, which is the product of the following two factors: one is the interaction coefficient Ki of the pile, and the second is the pile is fixed at the pile platform. The constraint coefficient Kr.
