摘要:
新建的南海岛礁工程在运营过程中将面临诸多维护方面的问题,进行科学的工程维护需要工程基础研究的支撑。本文分析了现有研究中海洋环境对岛礁工程结构与设施带来的影响,主要集中在以下三个方面:一是普通混凝土、珊瑚礁混凝土与金属结构在海洋环境的腐蚀与防治问题;二是由珊瑚岛礁地质及钙质砂特性带来的人造岛礁地基稳定性问题;三是台风、地震和海啸等极端荷载对岛礁工程的影响问题。随后,针对南海岛礁工程结构与设施在运营维护过程中可能出现的亟待解决的实际工程问题,文章给出了部分参考意见。

Abstract:
The newly constructed infrastructures on the Nansha islands would face many maintenance challenges in the process of operation. The optimal and feasible engineering maintenance requires the support from engineering basic research. This paper analyzes the influence of marine environment on the infrastructures, mainly focusing on three aspects. The first one is the corrosion and prevention of ordinary concrete, coral reef concrete and metal structure in the marine environment. The second one is the potential hazard of artificial island foundation due to the characteristics of coral reef and calcareous sand. The last one is the impact from some extreme loads like typhoon, earthquake and tsunami. Then, in the view of the practical engineering problems that may arise on those islands, some suggestions are given.
