摘要
泥石流是自然斜坡中常见的一种地质灾害,特别是砂泥岩互层的地层中,其在我国西南地区分布较为广泛.以松桃县永安乡沙堡村半沟泥石流为研究对象,在地质调查的基础上,通过对泥石流岩土体特征的研究,利用钻孔侧斜的方式对泥石流运动进行监测,深入分析泥石流发育特征.通过对泥石流发育特征与工程治理措施进行研究,为泥石流防治工程治理措施提供数据支撑.
Abstract
Debris flow is a common geological hazard in natural slopes,especially in the interbedded layers of sand and mudstone,which is widely distributed in the southwestern region of China.In general,once the excavation of the road cutting slope is carried out,a high and steep free surface is formed at the foot of the slope,which has a high possibility of instability.Taking the debris flow in Bangou,Shabao Village,Yong'an Township,Songtao County as the research object,based on geological investigation,the characteristics of the rock and soil mass of the debris flow are studied,and the movement of the debris flow is monitored using borehole inclination measurement,deeply ana-lyzing the development characteristics of the debris flow.By studying the development characteristics and engineer-ing governance measures of debris flows,data support is provided for the engineering governance measures of debris flow prevention and control.
