蒲丹快速路新建工程桥梁设计要点分析

Analysis on Design Essentials of Bridges in New Project of Pudan Expressway

摘要:

蒲丹快速路(S401线蒲江绕城段)新建工程属于比较典型的山区公路工程,其特点主要表现为地面高差大、山高沟深,变化频繁。本文主要介绍了项目的设计概况及桥梁设计要点。重点论述了本项目中装配式桥梁结构的应用、控制性节点工程的优化设计、京昆高速(成雅段)渡线工程设计、上跨蒲江河段桥梁结构设计、桥梁结构抗震措施的设计及桥台陡坡段边坡的防护设计。本工程的桥梁设计经验可为今后相关工程提供参考及借鉴。

Abstract:

The new project of Pudan Expressway (Pujiang Ring Road of S401 Line) is a typical mountain highway project, which is characterized by the large ground elevation difference, high mountains and deep ditches, and frequent changes. The design overview of the project and the design essentials of the bridge are mainly introduced. The application of prefabricated bridge structure, optimization design of control node engineering, design of Beijing-Kunming Expressway (Chengya Section) Crossover Project, design of bridge structure spanning the section of Pujiang River, design of bridge structure anti-seismic measures and protection design of abutment steep slope section are mainly discussed.
