摘　　要：为了定量分析病险水库均质坝在加固后的渗流稳定情况,基于非饱和渗流有限元理论,采用Geo Studio软件计算了加固后的腰石水库大坝在稳定及非稳定渗流状态下的渗透稳定,得到了坝体渗流场、渗透比降、渗流量、坝坡安全系数和最不利滑裂面。研究成果可为类似小型水库除险加固设计的渗透稳定复核提供借鉴。In order to quantitatively analyze a dangerous reservoir in homogeneous dam seepage stability after reinforcement, based on unsaturated seepage finite element theory, the calculation of seepage stability after reinforcement dam in steady and unsteady seepage condition by using Geo Studio software, the Yaoshi reservoir dam seepage field,seepage gradient, seepage flow, the safety coefficient of dam slope and the most dangerous slip surface. The research results can be used for reference for the seepage stability review of the similar small reservoirs.
