摘要
本文讨论了瞬态波作用下非线性岩土与非圆结构相互作用的问题。文中引用了一种多参数的非线性弹性岩土模型,应用复变函数方法求解了由小参数摄动展开得到的各阶渐近线性方程,并利用映射函数使计算得到简化。文中给出了瞬态波水平和垂直入射时直墙拱结构动力响应的位移和应力数值结果。
This paper deals with interaction between nonlinear geo-medium and non-circular structure due to transient wave. The behavier of the geo-medium is described by the nonlinear e-lastic model with multiple parameters. The analytic solutions of the asymptotic equations of each order obtained by small parameter perturbation are given by the complex function method. Numerical computation is simplified by the mapping function. The numerical results of displacements and stresses of arch-wall structure dymanic response to the horizontal and vertical incident transient wave are given in the paper.
