支架分级放大技术在Y型墩连续刚构桥梁中的应用

The Application of Bracket Grading and Amplification Technology in Y-Shaped Pier of Continuous Rigid Structure Bridge

在水中软弱地基上施工Y型墩墩柱及0#块,其混凝土结构尺寸较大,为了满足支架宽度在承台外的软弱地基上搭设,以实际工程为例,对分级放大支架进行设计,并对其具体施工进行探讨,推进支架体系的成功应用。

When the Y-shaped pier column and 0# block are constructed on the soft foundation in water, the concrete structure size is larger. In order to build a support to meet the width requirement on the soft foundation outside the bearing platform, this paper takes the actual engineering as an example to design the gtading and amplification bracket, and discusses its specific construction, so as to promote the successful application of the support system.
