摘    要:PLAXIS程序在渗流计算方面具有强大的功能.应用PLAXIS程序对水位下降过程中的边坡稳定性进行了数值模拟,分析了不同的水位下降速率及土体渗透系数对边坡稳定性的影响.分析结果表明,水位下降速率越大、土体的渗透系数越小,则越不利于边坡的稳定.

关 键 词:水位下降速率    渗透系数    边坡稳定性    PLAXIS程序

Abstract:The PLAXIS program has the powerful function of seepage calculation. The PLAXIS program is adapted to simulate the stability of a slope during the drawdown process of the water level, and effects of the drawdown rate of water level and permeability coefficients of soil on the stability of slopes are analyzed. Results show that the faster the drawdown rate of water level is, the smaller the permeability coefficients become and the more unstable the slope is.
Keywords:drawdown rate of water level  permeability coefficient  slope stability  PLAXIS program
