摘要
调研工程的环境、水文、耐久性设计和荷载设计资料,通过在工程建设期预埋入耐久性监测传感器,从建设期开始实时监测实体工程耐久性退化历程,获得基于实体工程的耐久性关键参数;建设工程配套暴露试验平台,开展与实体工程相同原材料和配合比的工程暴露试验研究与室内快速试验研究,研究实体工程-暴露试验-室内试验耐久性退化历程的差异,建立三者之间的耐久性退化指标相关性,指导我国海港工程混凝土结构的耐久性设计与施工质量控制。
The data of environment, hydrologic condition, durability design and load design are surveyed and collected.The durability monitoring sensors are embedded in the construction period to monitor the durability degradation from the beginning of the construction period to obtain key durability parameters of the project. The exposure test stations are built to carry out the exposure test investigation with the same raw materials and mix proportion to the project.While at the same time, the durability of the concrete also with the same raw materials and mix proportion to the project is carried on in laboratory. Therefore, the differences of the durability degradation among the projects, exposure tests and laboratory studies could be investigated and the relativity would be built. It could guide the design and construction of marine concrete structures.
