通过典型海洋潮差区的现场试验,分析了弯曲荷载对受压区和受拉区混凝土氯离子浓度及对流区深度的影响,研究弯曲荷载水平与不同受力区域混凝土氯离子扩散系数的关系。结果表明:弯曲荷载对混凝土氯离子扩散性能有较大影响,但对氯离子侵蚀的对流区深度影响不大;弯曲荷载水平与混凝土氯离子扩散系数之间的关系可以用二次多项式表述。
Through the test of the typical marine tidal zone field,the influence of the bending load on the concrete chlorion concentration in compression zone and tension zone,as well as the convection zone depth were analyzed,and the relationship between the flexural load level and the chlorion diffusion coefficient of different force area of concrete was researched. The results showed that the bending load had a great influence on the performance of concrete chlorion diffusion,but little on the convection depth of chlorion erosion; second-degree polynomial could be used to show the relationship between the diffusion coefficients of chlorion in the concrete and bending load level.
