高陡边坡变形及其对坝体安全稳定影响研究进展

高陡边坡变形及其对坝体安全稳定的影响，是高山峡谷型流域水利工程施工建设与安全运行所普遍面临的重要科学问题。一是高陡边坡稳定性研究，通过坝体两岸高陡边坡变形监测理论和方法研究，为实现动态反馈提供可靠的分析数据，再评价高陡边坡安全稳定性。二是高陡边坡变形对坝体安全稳定影响研究，通过分析岸坡与坝体间的相互作用，明确高陡边坡变形对坝体安全稳定的影响机制、作用范围和作用程度。在总结上述研究内容进展的基础上，归纳了本研究方向亟需解决的4个关键科学问题：时变监控方法、高精度数值仿真、智能优化反分析、边坡对坝体影响的理论计算方法，认为应进一步开展高陡边坡与坝体间相互影响机制及加固措施研究，为高陡边坡变形及其对坝体安全稳定影响研究提供思路。

Research advances in the deformation of high-steep slopes and its influence on dam safety

For the water conservancy project in the alpine canyon basin, the deformation of high-steep slopes and its influence on the dam safety are important scientific problems during the construction and operation period, which can be divided into two aspects. One is the stability of high-steep slopes, which can be evaluated by the reliable monitoring data obtained through the monitoring technology and methods of the high-steep slopes deformation. On the other hand, the effect of the deformation of high-steep slopes on the dam safety are also need to be studied. The influence mechanism, range and degree of the deformation of high-steep slopes on the dam safety are investigated through the interaction between the slopes and the dam. In the summary of the research progress in recent years, the time-varying monitoring method, four key scientific problems are concluded and proposed to be investigated, such as the high precision numerical simulation, the intelligent optimized inverse analysis and the theoretical calculation method for the influence of high-steep slopes on dam body. To provide ideas for the research, the interaction mechanism between the high steep slopes and dam body should be further studied as well as the strengthening measures.
