摘要
水电工程高陡边坡的工程地质、水文地质条件复杂,受施工干扰较大。当边坡规模较大、稳定安全性较差时,往往对项目决策、工程建设和运行安全影响很大。为此,论述了边坡工程地质条件对边坡稳定安全性的影响,阐明了确定边坡设计安全标准的原则,归纳了边坡常见的变形破坏模式及其分析计算方法,明确了边坡的开挖和加固处理的施工技术要求,并指出边坡勘察、设计、施工、管理一体化是目前边坡工程领域的热点课题和未来发展方向。
High steep slopes of Chinese hydropower projects have the characteristics of complex geological conditions and large scale, their stability plays a great role in decision-making, construction and operation safety of projects, and they are one of key technical issues for most of the hydropower projects in China. On the basis of analysis and review for reconnaissance, design, construction and operation experience of the slopes, author summarized the effects of geological conditions on slope stability and treatment, clarified the principle when deciding the safety criteria for slope stabilities, concluded the usual failure patterns of slope and the popular numerical simulation approaches for slope stability, put forward actual requirements for slope excavation and treatment construction, pointed out the integrity of reconnaissance, design, construction and management of slope is the pop issue at present and is the development trend in the future. Author hopes that the viewpoint and suggestion in this paper can provide useful information for the study, analysis, design and construction of slopes located in Chinese hydropower projects.
