已建立了重塑粘土的可压缩性、不排水剪切强度和渗透性与其Atterberg极限和活性之间的关联式。这些关系可用于在沉积之前对水力填充进行建模，例如细粒疏浚材料或尾矿。它们也可以用来估计正常固结的天然粘土的工程性质，如海洋沉积物。这种相关性涵盖了各种粘土的塑性指数和流动性指数。研究发现，活性对粘土的压缩性和不排水抗剪强度起主要作用，并与粘土的敏感性有关。活性显然不影响渗透性，但其他因素仍有待调查。由于可压缩性、不排水剪切强度和渗透率是相互关联的，因此可以得出结论：如果其中一个已知，则可以推导出另外两个。因此，这三种工程性质被视为不同的..。
Correlations have been developed which relate the compressibility, undrained shear strength, and permeability of remoulded clays to their Atterberg limits and activity. The relationships can be used to model a hydraulic fill, such as fine-grained dredged material or mine tailings, prior to deposition. They can also be used to estimate the engineering properties of normally consolidated natural clay, such as marine sediments. The correlations cover a wide range of plasticity index and liquidity index for a wide variety of clays. It was found that the activity plays a major role in the compressibility and undrained shear strength, and is thus also related to the sensitivity of clays. The activity apparently does not affect the permeability, but other factors remain to be investigated. Because compressibility, undrained shear strength, and permeability are interrelated, it can be concluded that if one is known, then the other two can be derived. Hence, these three engineering properties are seen as different...
