水布垭页岩软化特性的微观研究

Microscope Study on Softening Characteristics of Shale in Shuibuya Project

对水布垭页岩遇水后易于软化的原因，从矿物成份、结构特征和物化性质等方面进行的研究结果表明，高含量的粘土矿物是该类页岩易于崩解的物质因素，结构特征和微孔隙微裂隙的发育情况是其易于崩解的另外两个重要原因。

For finding the reason why shale in the Shuibuya project is easy to soften after immersion, a study has been performed in aspects of its mineral composition, structure characteristics, physicochemical properties etc.. The results show that high content clay mineral is a matter factor easy to disintegrate, and its structure characteristics and the development of micro voids and fissures are another two important reasons of disintegration.
