Abstract

A novel method is established to analyze the dike slope failure mechanism research in this paper. First of all, it improves a serial of operations, and boundary conditions for the genetic algorithm, such as the crossover operation, mutation operation, the operation and the convergence condition, then verifies the global search capability of the improved genetic algorithm with a complex function. Secondly, considering a calculation conditions with falling water levels, combined with the numerical analysis software FLAC3D strength reduction method, the critical state of Nanning city flood control embankment slope near the water surface is inverse analyzed when the water level drops. Finally, an analysis of the flood control dike typical slope failure mechanism under critical condition is also made. The results show that, the inversion analysis method of improved genetic algorithm combined with strength reduction FEM numerical analysis software FLAC3D is extremely effect, which has a powerful ability of global search. It’s also fast convergence speed, high accuracy and adaptability.
