| 摘 要： | 本文研究了动力边界单元法及其在土一结构动力耦合效应分析中的应用。文中利用Helmholtz势函数定理详细地推导了动力边界单元法的基本解,并且通过Laplace积分变换,应用直接列法建立了弹性动力的边界积分方程以及相应的数值求解公式。编制了动力边界单元法的计算机程序DYBEMI。最后对于不同激振频率和不同埋置深度的基础振动动力响应等算例进行了计算与分析。结果表明动力边界单元法在土一结构动力耦合效应问题中的分析是一种有效的方法。

| Abstract: | This paper describes the dynamic boundary element method and its application to the analysis of dynamic effects of soil-structure interaction. Based on the Helmholtz law of potential function, a fundamental solution to elastodynamics is derived by the direct method and the Laplace integral transform. The elastodynamie boudary integral equation is establshed. The computer program DYBEM1 is made.Several examples of the dynamic response of the foundation to diffe rent frequencies and embedded depth are calculated and analyzed. Their results show that the dynamic boundary element method is effective in the analysis of soil-structure interaction. boundary integral equation,potential function.Laplace transform |
