中文摘要：

通过采用基于拟合优化的边坡滑动面粒子群算法,计算分析了无黏性土和黏性土边坡的安全系数和滑动面,通过FLAC3D计算结果对比,指出拟合修正的粒子群算法具有足够的精度和速度,对求解边坡最优滑动面有一定的指导意义。

英文摘要：

Through applying the fitted optimized slope sliding surface PSO,the paper calculates and analyzes safety coefficients of the slope with and without lick soil. Through FLAC3 Dcalculating results comparison,the fitted modifying PSO posses enough accuracy and speed,which has certain guiding meaning for solving optimal slope sliding surface.
