摘要
本文用半解析元法分析了基础与地下孔洞动力相互作用问题,由于采用了水平两方向解析,仅在竖向进行离散的方法,使三维动力相互作用问题化成了一维数值计算问题,大大减少了计算工作量,通过大量的参数计算分析,初步探讨了基础与地下孔洞振动传递的一些规律,为进一步探讨地下结构的振动(尤其是地铁)对地面结构的影响提供了一个有效途径。
The dynamic interaction of foundation and underground hole is analyzed by applying half-analytic finit element method in the paper. With the method, the problem of three-dimensional dynamic interaction is transformed into a problem of one-dimensional one to calculate. Therefore, the calculating work is greatly reduced and the drawbacks of the finit element method can be overcome.
