摘要
从能量法的基本原理出发,用等效弹簧来模拟桩土的相互作用,考虑了等效弹簧的弹性势能,推出层状地基中单桩的一阶自振频率的计算公式,并通过工程实例检验其计算结果,结果表明,此法较等效深度法精度有所提高。
According to the principle of energy-method and considering the potential energy of equivalent springs, pile-soil interaction is simulated by equivalent springs. And the first natural frequency of pile in layered soils is derived in this paper. The result is verified by real project and the method has more precision than the equivalent-depth method.
