摘　　要：消落带岩体的损伤劣化直接影响库岸边坡的长期变形稳定.近年来,相关模拟库岸边坡消落带的水-岩作用的试验设备和测试技术逐步发展,消落带水-岩作用劣化效应及机理研究逐步完善,相关研究进展主要体现在如下4个方面:库岸边坡消落带水-岩作用试验方法从干湿循环逐步发展到考虑库水压力变化以及应力和水-岩耦合作用,但相关模拟复杂应力条件和库水环境耦合作用的专用仪器设备和方法亟待进一步研究完善;水-岩作用下各类岩石的劣化规律和微细观结构损伤演化特征得到系统研究,并建立了多种损伤劣化模型,但复杂赋存条件下库岸边坡消落带岩体损伤劣化与地层岩性、坡体结构的相关关系,以及消落带岩体的损伤劣化机理及模型亟待完善;在消落带岩体劣化现场测试方面,声波、回弹、探地雷达和钻孔成像技术逐渐得到应用,但相关适用于大范围、长周期的消落带岩体劣化现场测试及分析技术亟待完善;消落带岩体劣化已经逐渐成为影响岸坡长期变形稳定的因素之一,但消落带岩体损伤劣化诱发岸坡局部或者整体变形失稳的临界条件、变形破坏模式分析还不够系统.The damage and deterioration of the rock mass in hydro-fluctuation belt directly affect the long-term stability of the reservoir bank slope.In recent years,experimental equipment and testing techniques have gradually developed for simulating the water-rock interaction.The relevant progress is mainly in the following four aspects:The testing method of water rock interaction has gradually developed from simple dry-wet cycles to considering changes in reservoir water pressure and the coupling of stress and water-rock interaction,while the improvement of specialized instruments and methods for simulating complex stress conditions and the coupling effect of reservoir water environment are urgent.The degradation laws and microstructural damage evolution characteristics of various types of rocks under water rock interaction have been systematically studied,and various damage and degradation models have been established.However,the correlation between rock damage and the formation lithology and slope structure still need to be improved,as well as the damage mechanism and model of the rock mass in the hydro-fluctuation belt.Acoustic wave,rebound,ground penetrating radar,and borehole imaging technologies are gradually employed in situ testing of hydro-fluctuation belt rock mass,but testing and analysis technologies suitable for large-scale and long-term rock mass degradation need to be improved urgently.The deterioration of rock mass in the hydro-fluctuation belt has become a non-negligible factor affecting the long-term stability of bank slopes.However,the analysis of critical conditions and failure modes of bank slopes caused by the damage and deterioration of hydro-fluctuation belt rock mass is not systematic enough.
