摘要
堆石的抗剪强度并非与应力成比例,而是呈非线性关系。这种非线性关系将对边坡的稳定产生重要的影响。从DeMello及DuncanJ等对堆石破坏条件方面的研究成果及其表达式出发,运用遗传算法结合瑞典及毕肖普法对堆石边坡进行稳定分析,以寻求此类边坡的真实安全系数及其临界滑面。算例表明了非线性强度指标的影响及遗传算法的优越性。
The relation between shear strength of rockfill and stress is not the direct ratio relation, it is the non-linear relation. This non-linear relation has an important influence to slope stability. From the result and the expression of rockfill slope stability studied by De Mello and Duncan J, the rockfill slope stability is analysed by the genetic algorithm with Swedish and Bixiaopu method to seek a real safety factor and its critical slide plane of this slope. The calculated example shows the superiority of non-linear strength influence and genetic algorithm.
