摘要

为了分析地基剪切模量对列车引起的地基动应力的影响，利用移动荷载作用下弹性半空间内部的应力响应解，计算了两种不同速度、不同地基剪切模量时，列车引起的地基表面反力和地基动应力。在两种速度下，反力最大值均随地基剪切模量的增大不断增大。不同速度时，地基剪切模量对动应力的影响是不同的。

Abstract

In order to analyze the influence of ground shear modulus on train-induced dynamic stresses

the contact force between reaction of foundation surface and dynamic stresses induced by train are computed for different moduli at two speeds based on the solution of stress responce induced by moving load. It is found that the contact force decreases with shear modulus increasing for both speeds. But the variation of dynamic stress with shear modulus is different at different speeds.
