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.

海积粘土的孔隙率不随次生地基环境从原始环境变化过程而变化或增加，从而产生高敏感性和高压缩性，导致地表各种结构严重沉降变形的假设的验证受到挑战。硅质在粘性土的初始强度发展过程中占主导地位，二氧化硅与钙的反应存在最佳值。初始强度的显著发展不仅与孔隙总量的变化有关，而且与孔径分布向直径增大侧的变化有关。这种机制产生的孔隙表明，海相粘土的孔隙不随次生地面环境从原始环境变化的过程而变化或增加。
