论土体结构各层次的功能及其相互关系

土体广泛分布于地球的表层,是一个十分复杂的自然体。本文在论述了土体7个结构层次功能的基础上,从系统科学的角度阐述了各层次之间的辩证关系,包括低层次是高层次结构的基础;高层次对低层次结构的影响;层次间的协同作用;层次间交错、重叠与演变等。在与土体相关的研究工作和工程实践中,将土体作为一个系统进行合理的层次划分和分析,有助于复杂问题的简化,从而全面正确地掌握土体的工程性质及其形成机理。

ON THE FUNCTIONS OF SEVEN SCALE - LEVELS OF SOIL MASS STRUCTURES AND THEIR INTER- RELATIONSHIP

Widely distributed on the surface of the Earth, soil mass is a kind of quite complex natural solid bodies. This paper identifies the soil mass to have seven scale-levels of structural hierarchies. Based on the functions of each scale-level structure, the paper further describes the dialectic relationships among the different scale-levels of soil structure system from the point of view of systems science. The examination includes the basic function form the lower scale-level to the higher scale-level, the influence of the higher scale-level on the lower scale-level, the synergism of the higher and lower scale-levels, interlacing, overlapping and evolvement of the different scale-levels. The structural system can simplify complicated problems if the soil mass is regarded as a system and then divided into reasonable hierarchies for analysis during scientific research and engineering practice related to soil mass. Thus the engineering properties and corresponding formation mechanisms of soil mass can be comprehensively and correctly understood.
