| 中文摘要:松散土体是自然条件下地壳表层不断演化的产和的，土的产成环境及其演化决定着土体的基本特性，按其所处的地质－地理环境，土体的生成大致可分为同生环境、表生环境和里生环境，地质－地理环境的不断演化使土体的和性质向着差异性，层次性、不规则性、突变性等非线性特征增的方向发展，遵循生成－演化为主导、结构－性质－体系的研究思路，本文对我国南方常州的闽南三角区的软土及天津市和海口市的硬土分别进行了研究，并重点讨论了演化环境与土体结构特征和物理力学性质的关系。 |

| Abstract:As soil is the product of the nature,the property of soil is determined by the evolutionary environment.According to the geological and geographic setting, the evolutionary environments of soil can be divided into syngenetic environment, supergene environment and endogenic environment. Soil generally evolves toward the strengthening of nonlinear characteristics, such as differentiation, stratification, irregularity and mutation of soil structure and property. This research focuses respectively on the soft soil in Changzhou, Jiangsu Province and the triangular area of southern Fujian Province, and the hard soil in Tianjin and Haikou, Heinan Province, with emphasis placed on the relationship between the evolutionary environment and the structural characteristics of soil. |
