基于物元可拓模型边坡稳定性综合评价

Comprehensive Evaluation of Slope Stability Based on Matter Element and Extension Model

边坡稳定性综合评价是1个复杂的系统工程,单因素评价指标之间的矛盾不相容问题普遍存在,为解决此类问题,综合考虑影响边坡稳定性的多种因素,建立了用于边坡稳定性评价的物元-可拓模型,该模型是利用边坡稳定质量等级和影响因素构造边坡稳定性综合评价的经典域和节域物元,最终通过关联函数建立了用于边坡稳定性物元-可拓综合评价模型,有效地解决了此类矛盾不相容问题。

Slope stability comprehensive analysis is a complicated system problem, and contradiction among different single factor evalu- ations is universal. In order to solve the problem, considering the variety of factors that affect slope stability, this paper constructs mat- ter element and extension model for slope stability comprehensive analysis. In this model, the classical and limited matter elements are established by the slope stability levels and the influencing factors, and the model is made by correlation function. This model can solve the above contradictions efficiently.
