摘要
针对某水电站的复杂地质条件,利用SEEP/W软件对重力坝挡水坝段在两种工况下的渗流稳定性进行了分析。结果表明,该水电站以垂直防渗墙为主、水平防渗与排水、滤水措施相结合的防渗体系的布置结构合理,可以有效地降低闸基渗透压力和控制基础渗流量,能够满足地基的渗透稳定性要求。
For the complex geological conditions of a hydropower station, use SEEP/W software to analyze the seepage stability of the retaining dam section of the gravity dam in two conditions. The results show that the arrangement structure of seepage system depending on vertical antiseepage wall, combing horizontal anti-seepage with drainage, water filtering measurement, is reasonable, can effectively decrease the pressure of sluice foundation seepage and controls seepage flow, meeting the requirement of the seepage stability of foundation.
