公路桥台后复合地基加固处理研究

Study on Reinforcement of Composite Foundation Adjacent to Highway Abutment

通过京津高速公路天津段鱼塘范围内软土路段的桥台后高填土路堤地基加固设计及工后情况,考虑施工工艺及工序的影响,对软土地区桥台后高填土路堤采用现浇薄壁混凝土管桩与水泥搅拌桩结合使用,应用效果良好。

Through the foundation reinforcement design and post-construction conditions of high backfill embankment adjacent to abutment in soft soil section within fish pond area at Tianjin Section of Beijing-Tianjin Highway, taking construction process and its effect into consideration, cast-in-place thin-wall concrete tubular piles and cement mixing piles are used therein, getting good effect of application.
