【 摘 要 】

An analytical solution for chloride ions bilateral diffusion within concrete was developed based on Fourier transform method, by taking into account the bilateral diffusion and time-dependent chloride diffusion coefficient. The accuracy and applicability of the proposed analytical solution were validated by the field data after 10 years. Analysis results show that the ERFC is not suitable for solving chloride ions bilateral diffusion within concrete slabs exposed to the natural submerged environment. The proposed solution is in good accuracy to simulate the chloride concentration distribution within concrete in field site.
