Reservoir landslide surge disaster prevention and control method
The invention discloses a reservoir area landslide surge disaster prevention and control method, and relates to the technical field of water conservancy and hydropower engineering, and the method comprises the following steps: S1, obtaining the longitudinal geological section of a potential landslide mass, and calculating the horizontal movement speed of the potential landslide mass according to a vertical strip division method; s2, calculating the initial wave height of the landslide surge; s3, calculating the wave height of the propagation wave moving towards the protected object and the rise of the surge, and drawing a change curve of the wave height along the way; s4, a wave dissipation structure is arranged close to the boundary of the protected object in the wave front direction of the propagation waves, and the maximum height of the wave dissipation structure is larger than the height of the propagation waves at the arrangement position; according to the method, the propagation and attenuation characteristics of the landslide surge in the reservoir area are fully considered, the wave dissipation structure is arranged in a targeted mode to reduce the climbing wave impact energy to the maximum extent, the wave dissipation effect is improved, large-scale slope cutting and load shedding construction on the landslide mass is avoided, and the construction safety risk and the slope cutting and load shedding project investment are reduced.
本发明公开一种库区滑坡涌浪灾害防治方法，涉及水利水电工程技术领域，包括以下步骤：S1：获取潜在滑坡体纵向地质剖面，按垂直条分法计算潜在滑坡体水平运动速度；S2：计算滑坡涌浪初始浪高；S3：计算朝向保护对象运动的传播浪浪高和涌浪爬高，绘制涌浪浪高沿程变化曲线；S4：靠近保护对象边界沿传播浪波前方向布设消浪结构，消浪结构最大高度高于布设位置处传播浪浪高；本发明中充分考虑滑坡涌浪在库区的传播和衰减特性，有针对性布设消浪结构去最大程度削减爬坡浪冲击能量，提高消浪效果，避免了在滑坡体上进行大规模的削坡减载施工，降低了施工安全风险以及削坡减载工程投入。
