摘要
针对新建城市道路穿越既有高速公路的工程情况,结合工程实例,对新建桥梁上跨高速公路、新建地道下穿高速公路及高速公路路改桥三类方案进行详细分析。对各方案的特点及优缺点进行比较,为工程实施及今后类似工程提供设计参考。
Aiming at the situation that new urban roads crossing existing highways,combined with engineering examples, the paper analyzes three kinds of schemes of new bridge over crossing expressway, new tunnel underneath passing expressway and expressway-to-bridge in detail. The characteristics, advantages &disadvantages of each scheme are compared to provide design reference for the implementation of the project and similar projects in the future.
