摘要
本文采用有限元-局部透射边界方法在频域内求解了土与结构相互作用问题中的一个具体实用问题:地基动力刚度系数的计算。通过典型算例与解析解对比表明,此方法具有足够的精度。特别是对任意复杂形状的地基,此方法都具有解耦性质良好、易于在计算机上实现的特点。
In this paper a concrete practical soil-structure interaction problem-calculation of dynamic stiffness coefficients of foundation is solved with the finite element -local transmitting boundary method in frequency domain. The comparison of the method with the analytical one in a typical example shows a sufficient accuracy. Especially, for any foundations with complex shape this method has a good decoupling feature and is easily implemented on computer.
