东海大桥主通航孔斜拉桥索塔的施工技术

对国内已经建成的首座跨海大桥-东海大桥主通航孔斜拉桥主塔的施工技术进行了详细介绍,在100年设计基准期的前提下、面临恶劣海况的条件,为了确保跨海桥梁结构耐久性,采用了高性能混凝土。海上斜拉桥主塔施工,无论在施工技术,还是在施工管理上都是一次新的尝试和探索,此项工作十分重要和有意义,这将对我国21世纪跨海工程大跨度桥梁塔柱的施工提供宝贵经验。

Construction Technique of Cable-stayed Bridge Pylon of Main Navigation Span for Donghai Bridge

The article introduces in detail the construction technique of the main cable-stayed pylon of the main navigation span of Donghai Bridge - the first bridge crossing the sea and has been built in China. Under the premise of 100-year design datum period, facing the bad sea conditions and in order to ensure the structural durability of the bridge crossing the sea, the high-performance concrete is used. The construction of the main cable-stayed bridge pylon on the sea, whether in the construction technique or in the construction management, is all a new attempt and study. This work is very important and significant. The work will provide the valuable experience for the construction of the larger-span bridge pylon of the Twenty-one Century in China.
