悬空支撑体系在水上盖梁施工中的优化设计

Optimized Design of Suspension System for Cap Construction on Water

新建海河大桥南引桥墩柱较高且为方形墩柱、水上作业施工,若直接使用传统的施工方法很难确保盖梁工程的安全和质量。经过对传统方法的改进,对整个支撑体系进行了优化组合,通过材料的周转,在较经济的投入下,盖梁工程经过2个多月的施工,取得了预期的效果。优化设计后的悬空支撑体系,给类似工程的施工提供了一定的借鉴。

The piers of south side of the newly built Hehai bridge is high and square. If the traditional technique was directly adopted for overwater construction,it is difficult to ensure the security and quality of the project. After improvement of traditional technique,the whole sustain system is optimized. Under the economic investment,after the two months' construction,the expected target was achieved,the optimized sustain also can be used for the reference for similar project.
