摘要
水库蓄水后,岸坡在波浪、水流的冲蚀作用下被淘刷、磨蚀、搬运而发生变形坍塌。与无波浪作用下的坡面防护结构相比,有波浪作用下的防护结构还受到破波冲击力、水流回落引起的渗透反力等动水作用力。通过防护块体在有、无波浪作用力情况下的稳定性对比,来分析波浪对防护结构稳定的影响情况,确定防护块体大小并提出防护措施和建议。
After the reservoir stores water, the bank is easy to distort and collapse with the actions of scour, abrasion and transport produced by the waves and turbulent flow. Compared with the non-wave action situation, the protection structure with wave actions also bears the turbulence forces, such as the wave-broken impulse and permeation counterforce. Through comparing the reservoir bank revetment＇ s stability in the above two conditions, the waves＇ influence scope to it is analyzed, and the size of reservoir bank revetment is decided. Finally, some protection measures and suggestions are put forward.
