摘要
主五号墩钢吊箱下放是苏通大桥下部基础工程的关键技术之一,由于钢吊箱竖向刚度大,吊点多而且距离近,所以控制难度大.为此进行了钢吊箱下放工程中载荷跟踪方面的试验研究.
It is very difficult to lowering Su-tong Bridge-pier caisson under water because of great vertical rigidity and overall arrangement.Based on the mechanics analysis,the project was successfully completed controlled by computer with excellent control strategy.This is kind of new techniques in bridge construction.
