摘　　要：随着城市化进程不断加快,城市高架线路日益增多,堤防工程下穿既有高架线路情况频繁出现,堤路合一完善交通网络的理念逐步增强,常规的设计方案通常未考虑施工期间对桥下堤顶净空的要求,如何采取措施实现其功能成为设计优化的核心内容。本文结合实例围绕城市堤防工程下穿既有高架线路设计方案优化进行了研究分析,通过增加防浪墙,降低堤防填筑高度,增加联通路等措施对方案进行优化并取得显著效果。With the continuous acceleration of urbanization,the number of urban elevated lines is increasing,and the situation of embankment projects crossing existing elevated lines is frequent.The concept of integrating embankments and roads to improve the traffic network is gradually strengthening.Conventional design schemes usually do not consider the requirements for the top clearance of embankments under bridges during construction.How to take measures to achieve its function has become the core content of design optimization.This article combines examples to conduct research and analysis on the optimization of the design scheme for urban embankment projects crossing existing elevated lines.By adding wave walls,reducing the embankment filling height,and adding connecting roads,the scheme has been optimized and achieved significant results.
