| 摘 要： | 重约5800t的主5号墩钢吊箱下放是苏通大桥工程的关键，由于其竖向刚度极大，吊点距离设置较近，所以控制难度极大。如果载荷控制不好，就会影响结构的安全。本文阐述了钢吊箱下放施工中载荷变化的控制试验研究，以及对于载荷跟踪，所做的仿真。

| Abstract: | To lower the Sutong bridge pier caisson about 5 800 tons under water is a key point of this project. Due to great vertical rigidity and overall arrang ement, it is difficult to control the lowering process. It will affect the safety of the structure if load is not well controlled. The load-tracking approach on Sutong project is described and system simulation is presented too in this papers. |
