宝鸡渭河北岸大型深层黄土滑坡基本特征与稳定性研究
RESEARCH ON BASIC FEATURES AND STABILITY OF LARGE AND DEEP-SEATED LOESS LANDSLIDE ON THE NORTH BANK OF THE WEIHE RIVER IN BAOJI AREA
摘要
Abstract
The Yangjiacun large scale deep-seated loess landslide on the north bank of the Weihe River in Baoji area is taken as the research sample in this article.Field geological detailed survey,engineering geological exploration as well as high density DC resistivity geophysical exploration method were comprehensively applied to reveal the basic features and stability of the Yangjiacun landslide.The research findings indicate that:The Yangjiacun landslide is a deep-seated multiple rotational loess landslide with a general shape of circular arc characteristic sliding surface.The northern Weihe fault just passes through from the central part of the Yangjiacun landslide mass,which might control the structure features of the landslide.The deformation of the Neogene Sanmen formation clay layers serves as the main internal cause of landslide occurrence.Comprehensive evaluation results indicate that the Yangjiacun landslide mass generally is in a stable state;however,the local deformation of landslide toe should be paid attention to.The research results will provide basis for early warning and risk control of the Yangjiacun landslide.关键词
