陕北某黄土边坡工程地质特征研究

Study on the Geological Characteristics of Loess Slope Engineering in Northern Shaanxi

以陕北某黄土边坡为例,详细阐述了该边坡的工程地质特征,在此基础上分别从地形地貌、地层岩性、岩体结构、人类工程活动及降雨等多个方面分析了边坡的变形破坏机制。结果表明整体自然边坡目前稳定性差,处于极限状态,在继续开挖或者降雨、振动等外因素作用下,整个边坡极易再次发生大中型滑坡。

A loess slope of northern Shaanxi taken as an example,the geological engineering characteristics of the slope is elaborated,and the mechanism of slope instability is analyzed from many aspects such as topography,lithology,rock structure,human activity and rainfall. The results show that the stability of the natural slope is not good and it is in the ultimate state. The entire slope would easily fail again in the case of continuing excavation,rainfall,lower vibration or other external factors.
