摘要
水利水电工程在建设过程中和建成后的运营期间,不可避免地遇到大量滑坡体和边坡,这些边坡地震时极易发生失稳,将严重威胁水利水电枢纽工程安全。掌握边坡的地震失稳机理,采用合理方法防范此类灾害发生是确保工程安全的必要任务。本文从试验分析和计算仿真两个研究手段出发,查阅了大量文献,系统阐述了水利水电工程边坡地震安全研究的发展历程。并对这一领域的最新研究成果进行了归纳,评述了各类边坡稳定分析方法的优点和不足,展望了进一步研究需要加强的工作,着重指出了建立切实可行的边坡地震稳定性评价指标与安全标准是当前研究中最为紧迫的任务。
During the construction and after the completion of water conservancy and hydropower projects,a large number of landslide bodies and slopes are formed inevitably. These slopes tend to lose their stability during earthquakes, which will seriously threaten the safety of the projects, and then leads to heavy losses in people＇s lives and property. It is necessary to figure out the mechanism of slope seismic instability and adopt reasonable methods to prevent such disasters. This paper reviewed a large amount of literature by the two research methods of experimental analysis and numerical simulation, systematically expounded the development history of slope seismic safety in water conservancy and hydropower projects, summarined the latest research results in this field, discussed the merits and defects of various slope stability analysis methods, and pointed out the further work expected to be strengthened. Finally it is emphasized that it is the most urgent task to establish a feasible evaluation index and safety standard for slope seismic stability.
