成层土体与结构组合体系的动力数值模型

A Dynamic Numerical Model for the Combined System of Layered Soil-Structure

  • 摘要: 本文运用边界积分方程——边界单元法,分析并计算了具有成层土体与结构组合体系的动力耦合效应问题。提出了用边界积分求值的动力数值模型。它可以对不同土体情况(半无限单一土体、成层的和夹有淤泥层土体)和结构组合体系的动力响应进行数值求解。文中对具有成层土体的和含有淤泥夹层土体的结构动力响应以及填充不同填料的隔振沟的隔振效应等算例进行了计算和分折。结果很令人满意,其中某些结论具有一定实用价值。

     

    Abstract: The dynamic analysis and calculation for the Combined system of layered soil-structure by the Boundary Integral Equation-Boundary Element Method is presented and adynamic numerical model for the combined system is obtained using the boundary integration. It can be applied to numerical solution for dynamic responses of different combined system with various soil bases (Semi-infinite elastic soil, layered soil and soil interstratified withs ilt).Several numerical examples are calculated and discussed, including dynamic response of rigid structure with layered soil and soil interstratified with silt as well as screening effect of trenches with different type of backfill. Some satisfactory results and valuable conclusions are obtained.
