Comparison and Choice of Integrated Control Schemes for Landslide

In order to compare various landslide control schemes and find an integrated control scheme,an optimization approach is established based on entropy weight.Such factors as geological information,practical condition,engineering economy and environmental influence are incorporated.According to the opinion of experts,a comparison matrix is set up.Entropy of decision-making is used to determine the ideal point.The order of schemes is determined by calculating the close-degree and the distance between the four schemes and ideal point.Results show that the second scheme is the best one.Entropy of decision-making is a feasible and quantitative selection method,which ensures the objectivity of calculation process and results.
