增建二线铁路桥涵设计关键技术研究

摘要

This paper reviews briefly the upgrading project of Handan-Changzhi and Handan-Jinan railway and addresses the difficulties in the design of bridges and culverts of the added second line. With respect to the safety, economy and feasibility, the key technologies for the bridges and culverts are developed for the construction of the added second line railway. The key technologies are expected to offer guidance for the construction and enrich the experience of bridges and culverts design.%对邯长、邯济铁路扩能改造项目的桥涵设计进行简要概述，主要介绍增建二线铁路的桥涵设计难点。针对性地提出设计施工过程中的桥涵关键技术并进行研究，确保增建二线铁路桥涵的施工安全，并在保障既有铁路运营安全的前提下使设计施工方案经济合理。通过对关键技术的研究，以期对增建二线铁路桥涵的工程建设提供指导性建议，同时丰富桥涵设计经验。
