通过输入埃而森特罗波(EL Centro)地震波对边坡进行有限元瞬态分析,得到边坡在各个时刻的应力值.然后利用Mohr-Coulomb破坏准则,得到对应某一起始点的滑动面.并用瑞典条分法计算边坡安全系数的公式,使其作为目标函数,经过人工蜂群算法进行优化得到起始点,从而确定了滑动面并计算出边坡安全系数.最后,对各个时刻的边坡安全系数进行统计分析,得到边坡失效概率.
By using the EL Centro seismic wave, the stress of the slope at each moment is obtained by transient finite element analysis of the slope, and then the sliding surface corresponding to a certain initial point is obtained by using the Mohr-Coulomb failure criterion. The formula of slope safety factor is calculated by the Swedish bar method, which is taken as the objective function and optimized by artificial bee colony algorithm to obtain the starting point, so as to determine the sliding surface and calculate the slope safety factor.Finally, Slope safety factor for statistical analysis, the failure probability of slope.
