摘要
论述了以连续梁为基本体系的系杆拱桥设计与施工的相关经验,其内容主要对象是中承式及下承式系杆拱桥,论文中有关内容是实桥经验的总结,包括总体布置、拱梁尺寸,配索要求。施工方法是无支架施工工艺及转体施工工艺等;同时介绍了钢管拱肋灌注混凝土管内压力分布及利用连续千斤顶顶升或提升纵、横梁的新工艺。论文具有较强的实用性,可供读者参考。
The paper presents the design of the tied-arch bridge based on continuous beam and the construction practices. The subjects of the research are half-through tie-arch bridges and through tie-arch brides. The generalization of the bridge construction practices are made in the paper, including general layout, arch beam size and cable arrangements requirements. The construction method is construction technique without support and turning construction technique. The tube pressure state of the arch rib and the new techniques such as lifting and jacking-up longitudinal girder and beam using continuous jack. The paper is practical and helping for the readers.
