摘要: 在前人有关地质灾害的研究中,滑坡地质灾害以群体式出现的专业术语有"滑坡群"和"滑坡带"两种,但对其内涵的认识存在模糊性和局限性,缺乏层次性,多数情况下其只是对多个滑坡聚集的简称,没有体现出对地质灾害研究的指导意义。本文修正了"滑坡群"的概念,丰富了 "滑坡群"的内涵,将"滑坡群"与相同的局部构造、活动构造相联系,使"滑坡群"内部的个体滑坡、相同新构造活动区域"滑坡群"之间的对比成为可能,实现了基础地质研究与灾害地质研究的有机结合。在此指导下提出了"滑坡群"评价方法,包括局部构造样式以及形成机理、局部构造与地质灾害空间演化规律、"滑坡群"内部个体滑坡对比,并建立了"滑坡群"时空演化模式,为预测滑坡破坏过程提供依据。
