摘要
新建高速公路与原有高速公路网连接,将带来更多新、老路基加宽、拼宽带处理问题,特别是在西南地区山岭重丘地带,更多的新老路基加宽、拼宽位于高填方段内。详细介绍了高填方路堤新、旧路基施工方法,包括高填方路基加宽段高边坡稳定性计算,高填方路基加宽段施工存在的问题分析,高填方路基加宽段施工技术处理方案,有效保证了新、旧路基结合部位的工程质量。
The connection of new and old expressway network causes widening of new and old subgrade, treatment problem of widening strip, in particular, in mountainous heavy hilly area of southwest China, widening strip of more new and old subgrade is located in high fill subgrade section. The authors introduce construction method of new and old high fill subgrade, including stability calculation of high slope,problem analysis in construction, construction scheme for widening section of high fill subgrade, which ensure engineering quality in the binding site of new and old high fill subgrade.
