摘要
综合运用多级模糊评判理论、系统层次分析方法(AHP)和灰色关联分析方法等系统理论方法,结合某高速公路部分标段路基下伏岩溶勘察资料,建立了高速公路路基下伏岩溶稳定性的综合评判模型,并对其进行了二级模糊评判,评判结果较准确地反映了岩溶的稳定程度。该工程实践也证明了此评判方法的可行性和可靠性。为高速公路岩溶区路基稳定性评价提供了可行的思路和方法。
Combined with the data of exploration of karst in some sections of one highway line,multistage fuzzy synthetic judgment theory,analytic hierarchy process(AHP) and grey correlation coefficient analysis are used to build the model of synthetic judgment of the stability of karst and synthetic judgment of the twostage fuzzy is made. Result of the synthetic judgment precisely reflects the practical situation of the stability of karst. It is also proved by practical engineering that this evaluation method is reliability and feasibility. So it presents a practical approach for stability analysis of karst subgrade.
