摘要
顶进法施工,可以实现在不影响铁路运输的情况下,完成下穿铁路工程施工;国内铁路网络发达,许多公路、市政项目不可避免的与铁路交叉,目前,下穿铁路顶进框构桥较为常见的多为单孔、两孔连续式、两孔分离式框构,一般采用D型便梁加固法或纵横梁加固法,个别多孔框构桥或大跨度连孔框构桥多采用纵横梁加固法,通过工程实例进行铁路架空方案分析研究,验证了本项目的设计可行性与合理性,同时,为同类项目设计提供经验与参考。
The jacking method can realize the construction of underpass railway without affecting railway transportation. Domestic railway network developed, many roads, municipal projects and railway inevitably cross. At present, the most common jacking frame Bridges of under-crossing railway are single-hole, two-hole continuous and two-hole separated frame structures. In general, the method of D type beam reinforcement or vertical and horizontal beam reinforcement is adopted, and the method of vertical and horizontal beam reinforcement is adopted in some porous frame Bridges or long-span frame Bridges with continuous holes.Carries on the railway overhead project analysis and research through the engineering example, verifies the feasibility and rationality of the design of this project. At the same time, it provides experience and reference for similar project design.
