摘　　要：提出了一种新的搜索土坡临界滑面的优化方法——网鱼算法。该方法原理简单,具有较强的全局寻优能力。网鱼算法首先通过对较大范围内试算滑面作计算,得到局部最优值,然后再以局部最优为初值进行小范围、高密度的搜索,从而确定临界滑面。实例证明,该方法适用于复杂土坡的临界滑面搜索。A new method to locate critical slip surface of soil slop named Wang-Yu algorithm is proposed. This method＇s theory is intelligible, further more it has strong capacity of global optimum. Wang-Yu algorithm obtains the local optimum by calculating the trial slip surface in large-scale area, then takes the local optimum as initial value to proceed a small-scale and high-precision search in order to locate the critical slip surface finally. Two examples are given and the results are satisfactory. This method proved that it is applicable for complex soil slope.
