摘要
岩堆边坡是一类具有特殊地质条件的边坡,其自稳能力较差,在外界环境及人工扰动影响下极易失稳。基于模糊数学的基本原理,建立了岩堆边坡危险性的模糊综合评价体系。将滑坡危险性划分为五个等级,给出了各影响因素相对于边坡失稳的权重,并给出了计算各影响因素隶属度的隶属函数和专家评定结果。根据不同的危险性级别,可以选择相应的减轻对策。利用建立的模糊评价体系,对某岩堆边坡工程进行了综合评价,并给出了针对性的治理措施。
Talus slope is a kind of slopes with special geological conditions. Due to the poor stability, it will be extremely unsteady under the influence of the external environment and artificial disturbance. Based on the basic principles and methods of the fuzzy math, the fuzzy comprehensive evaluation system for hazard assessment of talus slope was set up. The hazard degree of landslide was divided into five levels. The weights of factors related to the failure of slope were given. A membership function for the calculation of the membership of factors and the results evaluated by experts were also constructed. The mitigation measures could be selected according to the different levels of hazard. Using the system, a selected talus slope was assessed and some constructive measures were put forward.
