整体道床目前在国内外均得到了广泛的使用,在运营过程中应及时对其进行日常的养护维修工作。但由于不同地域的施工条件、土质条件及施工方式等因素的不同,所针对采取的补强工法也不尽相同。主要有修补前期细微裂缝的表面涂膜法以及强度和耐久性都十分良好的压力注浆法及开槽修补法三大类。文章着重针对各类补强工法进行对比。
The overall track bed is currently widely used both at home and abroad, and should be routinely maintained and repaired in the course of operation. However, due to the different construction conditions, soil conditions and construction methods and other factors in different regions, the reinforcement methods adopted are not the same.

The article focuses on various types of reinforcement workmanship comparison.
