摘　　要：基床袁层是轨道的直接基础，是路基最重要的部分，受到列车动荷载的剧烈作用。所以基床表层级配碎石施工的成败关系到铁路设计目标值是否实现的关键，在没有成熟经验的情况下，在大面积施工前通过试验段确定其施工工艺是非常必要的。Bed surface orbit is a direct basis, and the most important part of roadbed,by the train load of intense dynamic role.so bed of crushed stone surface-level relationship between the success or failure of the railway designed to achieve the goal value is the key, in the absence of mature experience of the circumstances, in the area of pre-construction through the test of its construction technology is very necessary.
