摘要/Abstract

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。

关键词: 滑坡群, 局部构造, 地质灾害

Abstract: The group landslide disasters are described as landslide group and landslide zone in the previous studies of geological disasters, and the connotation of landslide group or landslide zone is fuzzy, limited, and discursive. In most instances, the two terminologies are merely abbreviations of multiple landslides, and lack of practical significance for the research of geological disasters. We revised the concept of landslide group and enriched the connotation of "landslide group" through taking the structure background into consideration. The evaluation method of landslide group has taken shape under the guidance of the revised landslide group concept. Thereby, it becomes possible to compare the internal individual landslide in the same group and landslide groups within the new tectonic activity area. Under the guidance of "landslide group", a "landslide group" assessment method is proposed. The "landslide group" evaluation method mainly includes the following aspects:local tectonic style as well as its formation mechanism; the spatial evolution of local tectonic and geological disasters; comparison of the internal individual landslides in the same "landslide group". Based on the study, "landslide group" space-time evolution model is established to provide the basis for predicting future landslide hazards.

Key words: landslide groups, local structure, geological disasters
