平原型河谷区水库绕坝渗漏问题分析

Analysis on Seepage around Dam of Reservoir in Plain Valley Area

绕坝渗漏问题不仅会影响坝肩岩体的稳定性,还会影响建库效益,结合塘头水电站坝址区工程地质条件,对其右岸绕坝渗漏问题进行了计算与分析。结果表明:坝区右岸虽存在绕坝渗漏现象,但通过计算得出渗漏量对水库效益影响微弱,尚不会对坝肩岩体的稳定性构成危害。

Seepage around dam will not only affect the stability of abutment rock mass,but also affect the benefit of reservoir construction.In combination with the engineering geological conditions of dam site area of Tangtou Hydropower Station,this paper calculates and analyses the seepage around dam on the right bank of Tangtou Hydropower Station.The results show that although seepage around the dam exists on the right bank of the dam area,the calculation shows that the amount of seepage has little effect on reservoir benefits and does not pose a hazard to the stability of the abutment rock mass.
