| 中文摘要: |
| 本文通过对饱和土中波动方程的分析，建立了一组描述混合边值问题的基础振动积分方程。所提出的一种简单、直观的方法可将其化为第二类Fredholm积分方程。文中详细研究了瑞利奇点的特性及其对积分方程求解结果的影响，从而使人们系统地分析饱和地基上基础振动特性和其它地基振动问题成为可能。 |
| 英文摘要: |
| Based on the theory of propagation of elastic waves in saturated soil, the dual integral equations describing the vibration of foundation are established. By using the method suggested by the authors, the equations can be transformed into the Fredholm integral equation of the second kind and can be solved numerically. The effects of Rayleigh singular points to the solution of the integral equations are studied in detail. |
