近代海相沉积型海域大桥施工关键技术研究

Key Technology on Cross-sea Bridge Construction for Modern Marine Sedimentary Environment:Research

近代海相沉积型海域是我国沿海典型地质条件,由于其构造独特和力学特性复杂,在建造大桥时必须采取针对性的措施.因此从跨海大桥施工的测控技术、桥墩桩基和栈桥寿命维护等方面出发,探讨沉积型海域跨海大桥施工的关键技术,并在平潭海峡大桥施工中得到了实际应用.

Modem marine sediment manifests the typical geological condition in China＇s coastal lines. Due to the special structure and the complicated mechanical properties of the sediment, the corresponding methods must be adopted in the bridge construction. Considering the measurement and control technologies in constructing cross-sea bridges, pier pile, trestle bridge and its life-span, the updated technologies of cross-sea bridge construction for modem marine sedimentary environments are investigated, and have been applied in the construction of the Pingtan Strait Bridge.
