We consider each sleeper as an abutment of opposite forces , rails on horizontal sleepers as a mock dispersed elastic ground beam model and trains as moving load on beams . geometric roughness and damping are not taken into consideration 将每根枕木考虑成一个支座反力,将横向枕木支承的钢轨模拟成离散的弹性地基梁模型,将列车考虑成一个作用在梁上的移动荷载。
Contrast with the results , the dissertation concludes that the axial loads of column have no essential variation , the variations of moments and shear forces of column are small under horizontal loads in contrast with the structure system in elastic ground , the moments and shear forces variation of column cannot be neglected , and the structure system with different foundation have the close degree variation 通过对比分析,本文认为水平力作用下交错桁架体系柱的轴力基本不变,弯距及剪力响应数值变化不大。竖直荷载作用下,与弹性地基计算结果比较,弯矩及剪力均存在不可忽略的变化,且不同形式基础其影响的程度基本相近。
