The verification of the hypothesis that the voids of marine clay do not change or increase with the process of the secondary ground environment change from the original environment, and as a result, high sensitivity and high compressibility occurs, leading to serious subsidence and deformation to the various structures on the ground surface was challenged.Silica is dominant in the initial strength development process of clayey soil, and the optimum value of silica exists in the reaction with calcium. The significant initial strength development is involved not only with the change of the total amount of voids, but also with the change to the increase side of diameter in pore size distribution. The voids produced by this mechanism suggest that the voids of marine clay do not change or increase with the process of the secondary ground environment change from the original environment.
