海相环境下海工混凝土优化设计与耐久特性研究

Research on Optimal Design and Durability Characteristics of Marine Concrete in Marine Environment

我国拥有3000000 km^(2)管辖海域,在当代三大尖端科技革命当中,海洋技术具有极为重要的现实意义。随着海洋开发以及沿海核电等大型海洋工程的开发与建设。海工混凝土的耐久性问题以及混合比设计优化已成为了目前学术界研究的重点。而当代海洋工程建设同样离不开水泥混凝土材料,因*匕对于耐久性高且混合比例合理的海工混凝土的研究迫在眉睫。因此,本文首先对于海工混凝土设计优化及耐久特性进行了研究。在海相环境下,大桥的墩身直接影响到整座桥梁的结构安全。因九笔者选择墩身作为研究对象,通过极差分析等数据对比方式对海工混凝土进行优化设计,并针对其耐久性能进行研究。在文章的最后,笔者提出了针对海工混凝土的侵蚀问题的防护措施。

China has 3 million square kilometers of sea area under its jurisdiction.Among the three modern cutting-edge scientific and technological revolutions,marine technology has extremely important practical significance.With the development and construction of large-scale marine projects such as marine development and coastal nuclear power.The durability of marine concrete and the optimization of mixing ratio design have become the focus of academic research.However,the construction of contemporary marine engineering is also inseparable from cement concrete materials,so it is urgent to study marine concrete with high durability and reasonable mixing ratio.In marine environment,the pier of the bridge directly affects the structural safety of the whole bridge.Therefore,the author chooses pier shaft as the research object,optimizes the design of marine concrete by comparing data such as range analysis,and studies its durability.At the end of the article,the author puts forward protective measures against the erosion of marine concrete.
