摘　　要：某水电站坝址覆盖层深厚且透水性较强,易形成液化沉陷等,因此开展坝基稳定应力和渗流稳定研究至关重要。笔者结合该电站复杂的地质情况,阐述泄洪闸坝段坝基稳定应力的计算分析,并采用不同的软件对泄洪闸坝段坝基渗流量及渗流稳定进行计算比对分析,为坝基地基处理和防渗设计提供依据。The overburden layer of a hydropower station is deep and permeable which is easy to form liquefaction subsidence.Therefore it is very important to study the stability stress and seepage stability of dam foundation.Combined with the complex geological conditions of the power station the author expounds the calculation and analysis of the stability stress of the dam foundation of the flood discharge gate dam section and uses different software to calculate and compare the seepage flow and seepage stability of the dam foundation of the flood discharge gate dam section so as to provide the basis for the foundation treatment and anti-seepage design of the dam foundation.
