针对软基特点及现有加固优选方法的不足,将模糊识别模式和变权综合模式相结合,建立了软基加固的灰色变权模糊优选模型,对某高速公路沿线软基加固方案进行优选,并采用综合健康指数评价法对优选结果进行检验。结果表明,灰色变权模糊模型的优选结果合理、可信,塑料排水板法为软基加固的最优方案。
According to the characteristics of soft foundation and the deficiency of the existing optimization methods, the fuzzy recognition model and the variable weight synthesis mode are combined to establish the gray variable weight fuzzy optimization model of soft foundation reinforcement. The optimization of the soft foundation reinforcement scheme along a highway is optimized, And using the comprehensive health index evaluation method to test the preferred results. The results show that the optimal result of gray variable weight fuzzy model is reasonable and credible, and the plastic drainage board method is the optimal solution for soft foundation reinforcement.
