浅谈高速公路桥梁改路基的优化设计

Discussion on Optimization Design of Transforming the Expressway Bridge into Subgrade

文章结合重庆九龙坡至永川高速公路(成渝高速公路扩能)JY1合同段冒水湖大桥桥梁改路基优化设计实例,针对该工程的地形地质与水文条件,分析了桥梁改高填路基方案的可行性,并提出了具体的变更设计方案,为高速公路桥改路优化设计、施工提供经验借鉴。

Combining the optimization design example of transforming Maoshui Lake Bridge into subgrade in JY1 contract section of Chongqing Jiulongpo-Yongchuan Expressway（ enlargement of Chengyu Expressway）,and according to the topographic geology and hydrology conditions of this project,this article analyzed the feasibility of transforming the bridge into high-filled roadbed,and proposed specific design change program,thereby providing the experience and reference for the optimization design and construction of expressway bridge transformation into the roads.
