Abstract: In order to grasp real-timely the stability of the soil slope, an evaluation analysis method was proposed based on the information of slope displacement monitor. The strength reduction method was used to describe the stability of the slope. A functional relationship between the strength reduction factor and the slope displacement was established based on the neural network algorithm using the data from the finite element numerical simulation as the train sample. By means of the function the strength reduction factor can be calculated from the monitored slope displacement to evaluate the slope stability. The effectiveness and practicality of the proposed method was verified with a group of numerical simulation data.

Key words: road engineering, slope stability, neural network algorithm, strength reduction method, slope displacement
