Model Study Evaluated The Safety And Durability Of Concrete Structures Of The Existing Harbor Pier

Durability of concrete structure is a hot spot in engineering field. At present, the native and foreign scholars have made a lot of study of the durability of concrete structure in atmosphere, and many of the results have been used in the engineering field, such as construction designs, durability evaluation of the concrete structure in service, decisions of the maintenance and reinforcement. But the study of durability of concrete structure in sea environment is just a little, and most of them concerning on the forecast of chlorine hydronium concentration and corruption investigations and analysis of the concrete structure in sea condition. Aimed at these instances, this text studies about the security and durability of existing concrete members in seaport. The primary content includes the following aspects:1) By the investigations and analysis of concrete structures in Ha Nan port, Tai Zhou port and Zhen Hai port, we find out the cause and disciplinarian debasing the capability of concrete structures.2) Based on the forecast model of chlorine hydronium concentration , reinforcing steel bar rusting rules, the changing disciplinarian of felting capability of reinforcing steel bars with concrete and the structure design principles of marine engineering ,this text sets up a bearing and cutting capacity appraising model of bending concrete members.3) According to the concrete structure rusting rules in the sea environment, the material of the structure and the inspecting data of the load, this text set up a reliability model of existing concrete bending members in port by using the credibility theory and the knowledge of probability and statistics,4) In the foundation of the erosion characteristic of concrete structure in sea...
