本文详细研究了粘弹性地基中刚性条形基础在竖向激励下的动力响应。一个先进的边界元算法，结合等参二次元素和一个复杂的自适应数值积分方案已被用于这项调查。考虑了均质半空间、半空间上覆地层和基岩上覆地层三种地基剖面。研究了泊松比和材料阻尼等材料特性的影响以及埋深和层厚等几何特性的影响。在土壤-基础界面的接触类型的效果也进行了研究。
In this paper, results of a detailed investigation on the dynamic response of rigid strip foundations in viscoelastic soils under vertical excitation are presented. An advanced boundary element algorithm developed by incorporating isoparametric quadratic elements and a sophisticated self-adapting numerical integration scheme has been used for this investigation. Foundations supported on three types of soil profiles, namely, homogeneous half-space, stratum-over-half-space and stratum-over-bedrock are considered. The influence of material properties like Poisson's ratio and material damping as well as the influence of geometrical properties such as depth of embedment and layer thickness are studied. The effect of the type of contact at the soil-foundation interface is also investigated.
