土体结构系统层次划分及其意义

土体结构系统研究是一项综合性、跨学科、具有重要理论和实践意义的基础性工作,它在尺度上涵盖了从宏观土区到微观粒子的整个土体系统。本文依据土体性质随尺度变化的原则,将土体结构系统从宏观到微观划分为7个层次,对每个层次的含义、研究内容和研究方法作了阐述。在分析了土体结构系统层次划分的意义后,进一步介绍了土体结构系统研究中面临的几个重要课题。土体结构系统的层次划分厘清了土体工程性质研究中的一些模糊认识,使土力学和工程地质学紧密结合在一起,为全面系统地研究土体结构系统打下了坚实基础。

HIERARCHICAL DIVISION OF SOIL MASS STRUCTURAL SYSTEM AND ITS ENGINEEING SIGNIFICANCE

Research on soil mass structural system is a comprehensive and interdisciplinary fundamental work which is of great theoretical and practical significance. It covers the whole soil mass system from macroscopic soil distribution area down to microscopic particulates from the angle of length scale. According to the principle that soil property changes with its corresponding length scale, soil mass structural system is divided into seven different structural hierarchies from macro to micro scopes in this paper. The significance, contents and research methodology of each hierarchy is explained. After the analysis on scientific meaning of a hierarchical division, several key subjects which will be met with in future research are introduced. Combining soil mechanics and engineering geology together tightly, the hierarchical division of soil mass structural system has not only cleared off some ambiguous understanding during the engineering property research of soil mass, but also laid a firm foundation for comprehensive and systematic research.
