摘要
本文从土与结构动力相互作用观点出发，用样条有限元和半解析无限元对地下隧道结构进行抗震分析，该方法具有降低维数、减少自由度、避免人为边界条件处理等特点，并可考虑复杂成层地基的情况。本文为探讨地下隧道结构-上相互作用内在机理提供了一个有效途径。
In this paper, the coupling method of spline finite element and semi-analytical in-finite element is extended to the solution for the seismic response of the underground. Thecoupling method not only has the advantage of reducing the dimensions and the number ofthe degree of freedom, but also can avoid the artificial boundary and has the capability ofconsidering the complex layer soil. The method presented herein provides a valid way to studythe mechanism of soil-underground structure interaction.
