摘要
针对不同材质、不同厚度、不同密度、一定脏污程度的道床做了动、静载试验 ,总结了静刚度试验结果。主要内容包括 :静刚度试验的理论基础、测试方法、静刚度的表达方式、测试数据的处理等 。
The stiffness of ballast is an important part in the whole track stiffness. To study the static stiffness of ballast under different conditions a series of tests were carried out. In the article the results including several equations are given, and the static stiffness of ballast under steady condition is put forward here.
