摘要
上库特殊的地形、地质条件决定了上库渗漏的严重性,水文地质参数是影响渗漏计算成果的关键因素,勘察设计阶段采用工程类比确定的计算参数可能存在较大误差。工程施工后,根据同一构造带在洞内的渗水情况,选择合理边界条件和概化模型可以反算构造带的渗透系数,反算后的结果表明,原渗漏计算采用的渗透系数是合理的,研究成果为防渗方案的最终确定提供了可靠的依据。
The special terrain and geological conditions of upper reservoir have resulted in serious leakage of upper reservoir.The hydro-geological parameters are key factors for seepage calculation,while there is a biggish error in calculation parameters confirmed by project comparison method during investigation and design phase.The hydraulic conductivity of tectonic zone has been back calculated through selecting reasonable boundary condition and generalized models after construction,according to the seepage situation in cavity of the same tectonic zone.The results show the hydraulic conductivity adopted in formerly seepage calculation is reasonable.The results have provided credible references for determining the seepage control scheme ultimately.
