摘要

顺层岩质滑坡作为滑坡的一种类型，在国内很多省份均有较高的发生频率，造成了较大的经济损失及不良的社会影响。为了研究顺层岩质滑坡发育的规律，依据笔者参与并成功治理的国内81处顺层岩质滑坡建立数据库，利用贡献率法将不同层面倾角区间的顺层岩质滑坡的各种相互关系进行定量化分析，以研究不同层面倾角区间的顺层岩质滑坡的相关性。结果表明，层面倾角为10°～25°的坡体，对顺层岩质滑坡贡献率程度最高；层面倾角为25°～35°的坡体，对顺层岩质滑坡贡献率程度中等；层面倾角为大于35°及小于10°的坡体，对顺层岩质滑坡贡献率程度最低。所得分析结论与实际情况吻合较好，能很好地为以后国内顺层岩质滑坡的研究及治理提供借鉴参考

Abstract

Bedding landslide is a type of landslides

it has higher frequency casualty of many provinces in China; it makes a lot of damage of economy and bad influence of society. In order to research regularity of bedding landslide

according to 81 bedding landslides in China to build data base that the authors engage in and successful control them

by using the contribution rate method to quantitatively analyze various interdependence about varied dip angle space of bedding landslide

the various correlations about varied dip angle space of bedding landslide are studied. It is found that the dip angles of bedding surface of 10°-25° have maximum contribution rate; the dip angles of bedding surface of 25°-35° have middling contribution rate; the dip angles of bedding surface greater than 35° or less than 10° that have minimal contribution rate. The research conclusions are consistent preferably with the fact

so as to provide potential gist to research and control bedding landslide in China in future.
