罗天乐特大桥受龙滩电站蓄水及上游连降暴雨影响,3#、4#主墩被淹于水下21m处,采用深水钢套箱接高墩身技术方案成为该桥能够最终建成的关键所在。文章就该桥深水钢套箱进行了有限元仿真分析,为类似工程的水下墩身施工提供参考。 Affected by the impoundment of Longtan Hydropower Station and continuous heavy rains at Longtan Power Station, the main pier of Pier # 3 and Pier # 4 was submerged 21m under the water. The technical scheme of connecting high pier with deep-water steel box was the key to the completion of this bridge Where you are. The article has carried on the finite element simulation analysis to the deep water steel box of this bridge, has provided the reference for the similar underwater pier construction.
