Analysis on the Stability Characteristics of Rock and Soil Anti-sliding in Unsaturated Soft Base Embankment

Aiming at the problem of poor stability of soft base embankment and low coincidence between the results of characteristic analysis and the actual results, a feature analysis method for rock and soil anti-sliding stability of unsaturated soft base embankment based on genetic algorithm is proposed. The stability coefficient is solved by using the weight and cohesion of rock and soil of soft base embankment. The genetic algorithm is used to calculate the rock and soil resistance of embankment. The characteristics of rock and soil anti-sliding stability of unsaturated soft base embankment are analyzed. Simulation results show that the shear strength of embankment soil in this paper varies from 20 to 46%, and the stability is good. The analysis results are more than 60% in agreement with the actual results, which is closer to the actual situation, verifying the effectiveness of this method.
