Abstract:
The characteristics of high cutting loess slope determine the special character of its siding surface when it is in unstable condition. It is discovered that the sliding surface on the section along slope shows L-shape. There is a big difference between calculation result and the real situation when computing by the conception of traditional safty coefficient. The mathematic method is used to simplify the sliding surface of high loess slope as “parabola” shape, the formula for stability analysis is educed, and the method for quickly searching the special silding surface is established. The aplication results show that this method can overcome the disadvantage of other methods.
