| 摘 要： | 三峡库区广泛分布的泥岩遇水易软化、崩解,致使许多库岸工程在水文涨落下出现病害。为了分析泥岩崩解特性及崩解机理,通过室内崩解试验,结合细观裂隙扩展规律及矿物成分的涉水特性,对泥岩崩解现象进行详细描述,阐释了泥岩崩解的机理。认为泥岩的崩解是裂隙扩展的过程,是与泥岩的沉积形成相反的过程;崩解可分为三个阶段:毛细裂隙吸水阶段、裂隙贯通阶段、二次崩解阶段;崩解物的颗粒粒径分布与泥岩颗粒中的矿物成分关系密切。

| Abstract: | The Gorges widespread mudstone is easy to soften and disintegration with water, this characteristic due to lots of problems with reservoir bank projects. Based in the laboratory disintegration test, combined with crack propagation law and geotechnical characteristics of the mineral composition of wading, mudstone disintegration phenomena described in detail and the mechanism of disintegration mudstone was illustrated. Results showed that the process of disintegration was the process of crack propagation and it deposited with the formation of the opposite. Disintegration can be divided into three stages, capillary crack absorbent stage, cracks connection phase and the second disintegration phase. The mineral composition greatly affects the particle size distribution of disintegration product. |
