水库岸坡地质灾害防灾减灾是库区生态环境尤其是地质环境保护的重要科学问题,通过对国内外研究文献的查阅分析并结合多年在三峡库区的研究实践,将水库岸坡地质灾害研究现状概化为水库岸坡稳定性变化、破坏机制、库岸再造预测方法等3方面,系统梳理了每个方面的研究情况。结果发现国内外学者高度重视库水位降落对岸坡稳定性与变形破坏特性的影响机制研究,基于卡秋金法提出了多个库岸再造预测新方法,但在库水位多旋回变动对岸坡作用、库水位周期性浸泡劣化岩土物理力学特性、类土质岸坡等方面研究不多。指出了水库岸坡地质灾害进一步研究应予以高度重视的3个方向,即水库岸坡地质环境效应、类土质岸坡变形与破坏和库岸地质灾害治理新技术新方法。
Reservoir geological hazards Disaster prevention and mitigation are important scientific issues in the reservoir area ecological environment especially the geological environment protection. By referring to the domestic and foreign research literature and combining with many years’ research and practice in the Three Gorges Reservoir Area, The status quo for the three aspects of the stability of the reservoir bank changes, damage mechanisms, bank and bank forecasting methods, systematically combing the research of each aspect. The results show that domestic and foreign scholars attach great importance to the study of the influence mechanism of bank water level drop on the stability and deformation and failure characteristics of bank slope. Based on the method of card fall gold, several new bank forecast methods are proposed. However, There is not much research on physical and mechanical characteristics of geotechnical such as periodic soaking of reservoir water level and so on. The paper points out three directions that should be paid more attention to in the further research of geological hazards of bank slope, that is, the geological and environmental effects of reservoir bank, the deformation and destruction of soil-like bank slope and the new technology for the treatment of reservoir bank geological disasters.
