摘要
杭州湾跨海大桥南岸滩涂区宽9.7 km,引桥采用栈桥法施工,下部结构为钻孔桩基础。滩涂区软弱地层厚,地形多变,地下局部有浅层气,潮汐对承台施工影响很大,施工条件复杂。主要介绍滩涂区承台吊箱围堰设计和施工技术。
The tidal-flat area on the south bank of Hangzhou Bay Sea-Crossing Bridge measures about 9.7 km wide. The approach spans of the Bridge there are constructed with construction trestle method, and the foundations of substructure of the approach spans are used with bored piles. In the tidal-flat area, the soft stratum is thick, landform is variable, there is shallow gas stratum under local parts of the ground, the tides affect a great deal the construction of the pile caps, and in a word, the construction conditions of the pile caps are complicated. In this paper, the design and construction techniques for the steel boxed cofferdams for construction of the pile caps in the tidal-flat area are mainly dealt with.
