中文摘要：

土石坝的渗流与坝坡稳定是影响土石坝长期安全运行的一个重要原因。运用有限元软件Geo—Studio2012以及Autobank7．41对某土石坝渗流稳定进行数值模拟分析，并采用水力学法以及瑞典圆弧法对其结果进行对比。结果表明，该土石坝坝坡稳定，3种计算方法的最后结果非常接近，同时都位于安全范围之内。相比而言，软件计算有着更大的安全空间，计算更加方便快捷，在今后土石坝渗流稳定分析中会具有广阔的应用前景。

英文摘要：

Both seepage and dam slope stability of the earth-rock dam are important factors to impact the long-term and safe operation of the earth-rock dam. By application Geo-Studio2012 and Autobank7.41, the numerical simulation analysis is performed for the seepage and stability of one earth-rock dam. Furthermore, the analyzing results are compared with those of calculation by the hydraulics method and the Swedish arc method. The calculation results show the earth-rock dam slope is stable and they are very close. Meanwhile, they all are in range of the safe values. Comparing each other, calculation by software is with larger safe room and calculation is convenient and less time consumption. The software will be with wide application prospect in the seepage and stability analysis of the earth-rock dam in the future.
