干湿循环下泥岩结构与强度破坏研究综述

干湿循环作用是水-岩作用的一种，它使泥岩变形，产生裂缝，致其结构损伤，这种损伤不断积累，泥岩最终发生崩解，进而造成强度衰减。泥岩作为滑坡的岩体类型之一，研究其在干湿循环作用下的结构劣化和强度衰减规律对分析库岸边坡和路基的稳定性有积极作用。通过多篇文献中对泥岩在干湿循环条件下的综合研究，从宏细观分析了泥岩的结构劣化机制，并总结了泥岩在干湿循环条件下的强度衰减规律及其与泥岩结构劣化的内在联系。

Review of the Damage Research of Mudstone Structure and Strength under Dry-wet Circulation

Dry-wet circulation is a kind of water-rock interaction, which causes deformation, cracks and structural damage of the mudstone. When this kind of damage accumulates continuously, it makes mudstone disintegrates eventually resulting in strength degradation. Mudstone, as one of the landslide rock types, to study the law of its structure and strength degradation under dry-wet circulation has a positive role for the stability analysis of the slope and subgrade. Through many articles studying mudstone comprehensively under the condition of dry-wet circulation, the structural degradation mechanism of mudstone has been analyzed from macro and micro views and the strength degradation law of mudstone under the condition of dry-wet circulation and its inner link with its structural degradation have been summarized as well.
