| Abstract: | In this paper, the coupling method of finite infinite element is applied to analyze the interaction of soil-underground tunnel system Compared with other methods, the presented method has the advantage of more satisfactory precision and less amount of computation The range of finite region and the location of middle point of the infinite element are studied, and the dynamic response of underground tunnel in the soft soil is discussed It is shown by numerical examples that this analytical model has high accuracy and significant economy |
