摘要
通过FLAC3D软件建立边坡三维数值模型,研究了边坡三维方向长度对安全系数的影响。研究结果表明:边坡三维方向长度越小,边坡安全系数越大,随着三维方向长度增大,安全系数逐渐降低并最终趋于定值;当边坡三维方向长度小于边坡高度时,安全系数下降明显,边坡体三维方向长度对其稳定性影响明显;当三维方向长度不小于边坡高度时,安全系数变化不大,边坡体三维方向长度对其稳定性影响趋于稳定。
A 3D numerical model was established for slope with FLAC3 Dsoftware so as to explore the influence of length in three-dimensional direction of the slope on the factor of safety. It is shown that a smaller length in three-dimensional direction will lead to a higher factor of safety,which will then decrease gradually with an increase in the value of length and tend to be stable at last. As the length is less than the slope height,the factor of safety decreases obviously,indicating the length in the three-dimension direction bringing in great effect on the slope stability. However,as length is no less than the slope height,little change occurs in the factor of safety,indicating the effect of length on the slope stability tends to be stable.
