汇海路大桥是当前我国最大的蝶式拱桥,构造复杂,建于浅海淤泥中,施工难度巨大,较差的软基又给该桥的桩基、接柱、承台、支架等工序的施工增添了更大的难度和更多的风险,其中的箱梁现浇支撑体系为重中之重,事关上部结构能否顺利安全的建成,本文通过对该桥箱梁支撑体系的优化过程和成功经验进行介绍,期望能为大家提供一些有益的参考。 The Huaihai Road Bridge is the largest butterfly arch bridge in our country. Its structure is complex and it is built in the shallow sea silt. The construction is very difficult. The poor soft foundation gives the construction of the pile, post, cap and support of the bridge A greater degree of difficulty and more risks, of which the box girder cast-in-place support system is the top priority, the completion of the upper part of the structure can be safely and safely completed, this paper through the box girder support system optimization process and success Experience is introduced, I hope we can provide some useful reference.
