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.
