基于可拓理论的边坡稳定性评价研究

岩体边坡的稳定性是受多种因素共同影响的复杂巨系统,通过某种方法对边坡稳定性进行合理、准确的评价一直是岩土工程研究的重要内容。基于物元理论和关联函数,将可拓理论引入到边坡稳定性评价当中,提出了边坡稳定性评价的可拓方法。以某实际边坡工程为例,在合理选取能够反映边坡岩体综合特性指标的基础上,建立了边坡稳定性评价的可拓模型,并且将预测结果与传统的模糊评判结果进行了对比。对比结果表明该评价方法能够较准确地反映边坡的稳定性状况,证明了该方法可行性。

Research on Evaluation of the Slope Stability Based on the Extension Theory

The stability of rock-mass slopes is a very complicated system which is controlled by lots of factors.It is always a very important research subject to evaluate the slope stability reasonably through some evaluation methods.Based on matter-element theory and dependent function,the extension theory is applied to evaluate the stability of rock-mass slope,and the extension method for the stability of rock-mass slopes is proposed.Taking a real slope project for example,based on the reasonable selection of evaluation factors of slope stability,an extension model for evaluation of slope stability is built,whose result is contrasted with the fuzzy evaluating one.As a result,it is practical and feasible to apply the extension method to estimate the rock slope stability.
