摘要
本文采用特解边界元法，分析了地基弹性和重力坝坝踵水平裂缝对坝体自振特性的影响，并将特解边界元法推广应用到两个区域问题。所得结论为工程设计提供有价值的依据。
In this paper,the effect of foundation elasticity and horizontal cracks in heel of gravity dam on autooscillation characteristics of embankment is analyzed. And particular solution bound-ary element method is extended to solve two region problem.
