杭州湾跨海大桥南航道桥主塔承台施工

Construction of Pylon Bases of South Channel Bridge of Hangzhou Bay Sea-Crossing Bridge

杭州湾跨海大桥南航道桥主塔承台为哑铃形结构,平面尺寸大。针对本海域恶劣的施工环境,大型承台采用分块施工方案,以降低海上施工难度,规避施工风险。

The pylon bases of the south channel bridge of Hangzhou Bay Sea-Crossing Bridge are designed in shape of dumbbell structures that are extraordinarily large in plan. In the light of the harsh construction environment of the pylon bases of the Bridge at sea, the scheme for construction of the large pylon bases in segments is adopted in order to reduce construction difficulties and avoid construction risk there.
