| 摘 要： | 土结构是一种物质状态，可以层次式的概念模型加以确定。从图象处理角度，提出了微结构定量研究的技术路线，确定了结构要素的量化方法。通过分形结构分析，探讨了天然结构和压力对黄土湿陷性的影响、水与土样之间的作用规律及其湿陷效应，提出了分形结构的湿陷性控制机理。

| Abstract: | The soil microstructure is a kind of states of substance, which cou ld be described with a conceptual model possessing tree structure. Based on ima ge processing technology, a technical way to quantify the microstructure and a method to determine the indefinite structural factors are put forwards. By analysis of fractal geometry, the influence of natural structure and pressure on the subsidence of loess and the regularities of reaction between water an d soil have been studied. And then the mechanism for control on the subsidence due to fractal structure is suggested. |
