摘 要:为解决土地资源匮乏环境下,桥涵结构物台背回填与路基填筑难以同步施工问题,与桥梁台帽、耳背墙施工、梁板架设等工序脱节问题,采用优先实施桥涵台背回填及过渡段路基的方法,使各项工序相互协调、连续,缩短工序转换周期,提高施工效率。同时,延长了桥涵台背回填自然沉降期,有效预防工后沉降、桥头跳车等质量隐患。In order to solve the problem that the backfill of the bridge and culvert structure is difficult to synchronize with the subgrade filling under the background of lack of soil resources, as well as the disconnected problem from the construction of bridge abutment cap, ear back wall, beam & slab erection and other processes, it is the implementation priority to the bridge and culvert backfill and the transition section subgrade, so that the various processes can be coordinated and continuous,shorten the process conversion cycle, and improve the construction efficiency. At the same time, the natural subsidence period of backfill of bridges and culverts is extended in order to effectively prevent potential quality hazards such as post-construction subsidence and bridge jumping.
