The rapid reinforcement technology of super-soft fill soil in the port area is a technical treatment method for the rapid reinforcement of the super-soft fill soil in the reclamation project.The technique can be applied in a short time without destabilizing the foundation.Compared with traditional vacuum preloading method,it has great engineering advantages.Combined with the engineering example of soft foundation treatment project in Quanwan port area,we preliminarily determine the design parameters according to the experience,and predict the bearing capacity of foundation.By further optimizing the design parameters,we compare and analyze the effect of soft foundation reinforcement under three kinds of drainage plate spacing.The optimal design parameters are determined by combining engineering cost,reinforcement effect and design safety reserve.
