According to geological characteristics and formation mechanism of Xigoukou Landslide

the calculation and evaluation of landslide stability are performed in consideration of four kinds of loading conditions by transmitting coefficient method and FEM. Based on the results of stability analysis

the anti-slide piles and ground drainage are adopted as the harnessing measures of landslide. Some harnessing schemes are formed based on the results of transmitting coefficient method and FEM as the study samples for the evolutionary neural network. The landslide stability and construction cost of these harnessing schemes are evaluated respectively; and the nonlinear relationship of the designing parameters of anti-slide piles with safety factors and construction costs is established. Through the genetic algorithm

optimum designing parameters of anti-slide piles are searched out from above schemes; and the most optimally harnessing scheme is achieved. The stability examination and analysis by FEM show that this optimized scheme can satisfy the design requirements; and it is effective and economic to the landslide harness.
