【摘要】 随着模糊数学引入到岩质边坡稳定性分析中,已取得多项成果,但评价专家主观意识对评价结果的影响较大、评价因素覆盖面不全,因此评价系统对岩质边坡的针对性不足等问题始终存在。对此,在将岩体质量分级法和卸荷岩体力学理论引入到模糊评价系统的基础上,提出一种基于有限元分析的边坡稳定性模糊评判方法。该方法在增加和修正评判因素的同时,通过有限元模型的计算结果分析,选取适当的参照量,将某些因素影响进行定量化处理,从而确定这些因素的权重比,减少专家评分中主观上造成的偏差。结合实际工程的分析过程显示,该方法实际操作性较强,对岩质边坡的分析更具针对性,能使得较多的影响边坡稳定性因素参与评判。更多还原

【Abstract】 With the introduction of fuzzy mathematics into rock slope stability analysis,many research results have been achieved.But the subjective consciousness of evaluation expert influences the evaluation results much too great.The covering surface is incomplete,and that the pertinence of evaluation to rock slope is not enough is already existed.Based on introducing rockmass quality classification method and unloading rockmass mechanics to the fuzzy evaluation system,a kind of fuzzy evaluation method of slope stability based on finite element analysis is proposed.This method has already increased and modified the judgment factors,meanwhile,through analyzing the calculation results of finite element model,it can select some contrastive relationships of influence factors quantitatively.Dealing with some factors in quantificationi,t determines the weight ratio so as to reduce the subjective deviation during the expert scoring.Combined with specific engineering example to check analysis,the actual operation of this method is much better.It has much more pertinence for analysis of rock slope,and it can make much more factors which will influence slope stability to judge the rock slope stability.更多还原
