METHOD FOR DETERMINING THE MOST RISK SLIP SURFACE OF LOESS SLOPE BY GENETIC ALGORITHM AND ITS APPLICATION TO STABILITY ANALYSIS

Loess landslides, especially those induced by earthquakes,are always the one kind of outstanding geologic hazards in the vast loess areas of West China . According to the basic idea and principle of genetic algorithm, a new metho d for determining the most risk slip surface of a loess slope is established. The test results show that the method is more effective and practical in the stability analysis of a loess landslide than traditional methods.
