近五年来,动力基础的理论工作在国内有了较快的发展和进步。基床系数法(即地基刚度系数法)正在由质弹模式向质弹阻模式转化,并出现了一些实测反算刚度与阻尼的方法。半空间理论的传入推动了方程对等法与耦合振动相位法的产生,动力桩基研究也有了我国自己的萌芽。这一局 In the past five years, the theoretical work of the power base has been rapidly developed and advanced in China. The base bed coefficient method (ie the foundation stiffness coefficient method) is transforming from the mass bomb model to the mass resistivity mode, and some methods for measuring back stiffness and damping have emerged. The introduction of the half space theory promoted the generation of the equation equivalence method and the coupled vibration phase method. The study of the power pile foundation also had its own sprout. This game
