1.前言近年来,在公路桥方面由于对行车性能重视及交通量的增大关系,带来的问题是伸缩缝寿命缩短。因而,采用多跨连续梁形式的计划有增大的趋向。对于砼桥的多跨连续梁的施工已有将各跨分段施工、最后以合拢段加以连接的施工方法。本文就是根据此施工方法叙述在支架上用弗莱西 1. Foreword In recent years, due to the emphasis on driving performance and the increasing traffic volume in the aspect of highway bridges, the problem brought about by the shortening of service life of expansion joints. As a result, there is an increasing tendency to adopt plans for multi-span continuous beams. For the construction of multi-span continuous beams of concrete bridges, cross-section construction has been carried out, and finally the construction method of connecting with the closing sections has been adopted. This article is based on the construction method described in the stent Flesh
