The dynamical test and the ultrasonic transmission are the main tests of the pile foundation now. 动力检测法和声波透射法是目前检验桩基础质量的主要形式。
Furthermore, a mass of numerical calculations of the internal force of pile group under different magnitude and obliquity loads is made by the program. 此外,采用本文程序对不同荷载量级及倾角下群桩基础的内力进行了大量的数值计算。
