RM水电站泄洪雾化特性及边坡防治对策

Protective Measures for Slope Prevention and Atomization Characteristics of RM Hydropower Station

RM水电站位于高海拔、低气压地区,工程泄洪具有高水头、高流速、大泄量等特点。泄洪消能区河谷狭窄,岸坡高陡,碎裂岩体广布,岩体卸荷裂隙发育,泄洪雾化对消能区边坡稳定影响较大,工程边坡防治对策尤为重要。本文依据Matlab计算的雾化分区分级的结果,分析了RM水电站泄洪雾化特点,对泄洪雾雨情况下边坡稳定性进行分析及评价,提出了雾雨区边坡合理可行的综合防治对策。

RM hydropower station,located in high altitude and low atmospheric pressure areas.Its flood discharge has the characteristics of high water head,high flow velocity and large discharge.The valley in the flood discharge area is narrow,the bank slope is high and steep,the fractured rock mass is widely distributed,the unloading and fissures of the rock mass are developed,and the flood discharge atomization has great influe nee on the slope stability of the energy dissipati on zone.The prevention and protective measures of the slope are particularly important.The paper using matlab software,analysed the characteristics of flood discharge and atomization of RM hydropower station based on numerical simulation.The grading of flood discharge atomization of RM hydropower station is obtained.The slope stability under the condition of atomization is an alyzed and evaluated and the reas on able and protective measures for the slope are proposed.
