Method Study Based on Entropy Weight Law for Stability of Loess Slope

In the comprehensive assessment, the establishment of assessment system and the determination of weight are both very important and difficult. In view of this situation, a new loess slope stability evaluation model is established. Loess slope stability condition will be divided into state-level 5.. stability, more stable, less stability, instability, unstable in this model. The evaluation factors are height of slope, gradient of slope, severe, internal friction angle and cohesion. Aiming at the difficulty of defining weight value, the Entropy Weight Law is used in the comprehensive assessment,which avoids the subjectivity of artificial weight.. The engineering example indicates that the new assessment method is reasonable and feasible, and it provides a new idea for slope assessment.
