基于“安全+”功能的混凝土海塘全寿命研究综述

Research Review on Concrete Seawall Full Life Cycle Based on"Safety Plus"Function

安全可靠的生态海塘系统是沿海城市发展的重要基础。文章分析了浙江省混凝土海塘的现状,结果表明,堤身混凝土结构普遍遭受离子腐蚀,寿命设计未考虑多目标优化,挡墙消浪效果有待提升;从海塘安全设计、结构形式和安全监测三个方面出发,综述国内外研究现状,并指出基于“安全+”功能进行多目标优化设计,有待进一步研究开发新式低碳固废海塘结构,建立基于工情、潮情的多维度、全要素海塘工程安全监测体系。

Safe and reliable ecological seawall system is an important foundation for the development of coastal cities.This paper analyzes the current situation of concrete seawalls in Zhejiang Province.The results show that the concrete structure of the embankment is generally subjected to ion corrosion,the life design does not consider multi-objective optimization,and the wave dissipation effect of the retaining wall needs to be improved.From three aspects of seawall safety design,structural form and safety monitoring,the research status at home and abroad is reviewed,and it is pointed out that the multi-objective optimization design based on"safety plus"function needs to further study and develop new low-carbon solid waste seawall structure and establish a multi-dimensional,fullfactor seawall engineering safety monitoring system based on engineering conditions and tidal conditions.
