叠片体是粘土矿物在土中存在的基本形式,也是粘性土结构重要的基本单元。实际上粘土矿物是以其叠片体来影响工程性质的,影响程度在不同的结构体系中是有差别的。在重塑土中由于结构具有以叠片体表面溶剂化层间接接触为主的特征,矿物叠片体的本性得以充分显示,故粘土矿物组成对工程性质的影响比较显著。在天然的原生结构土中矿物叠片体的本性受到制约,因而对工程性质影响的不及重塑状态明显。所以在评价粘土矿物对粘性土工程性质影响时,必须结合土的结构特征统一考虑。
Laminated body is the basic form of clay mineral in soil, and it is also an important basic unit of clay soil structure. In fact, clay minerals affect the engineering properties with their laminations, and the degree of influence is different in different structural systems. In the remolded soils, the nature of the mineral laminations is fully exhibited due to the fact that the structure is dominated by the indirect contact of the solvation layer on the surface of the laminations, so the composition of the clay minerals has a significant effect on the engineering properties. The nature of the mineral laminations in natural native structure soils is constrained, and thus the impact on engineering properties is not as pronounced as the remodeling state. Therefore, when evaluating the influence of clay minerals on the engineering properties of cohesive soils, it must be considered in conjunction with the structural characteristics of the soil.
