| 摘 要： | 随着我国高速铁路迅猛发展和原有普通铁路的提速,动荷载对支挡结构影响显著增大,现有的设计计算理论是否满足新条件要求,是现在的设计单位和科研单位需要解决的问题.为了弄清动应力对支挡结构的影响大小及范围,我们设计了实尺寸的动态试验模型,通过实验实测得到了不同的距离、不同加载幅度下的荷载图示.并据实验数据及现有的计算理论提出了减小动土压力的措施,且用挡土墙中两个重要参数Kc,Ko做了验证.

| Abstract: | With the rapid development of China's high-speed railways and speed elevation of the original ordinary railway lines,the influences of dynamic load on the retaining structures have significantly increased.Whether the existing theories of design and calculation can meet the requirements of the new conditions is a problem that the current design and research institutions need to resolve.In order to clarify the size and scope of the influences of the dynamic stress on the retaining structures,a real-size dynam... |
