农业水利建设中黄土边坡抗震分析

Seismic Analysis of the Loess Slope in the Agricultural Water Conservancy Construction

地震过程中,地震力的方向是不定的,仅考虑水平的地震力对黄土边坡的影响,具有明显的不足。利用地震角的影响,把地震力分解到潜在滑动面的法线和切线方向,计算相应的地震力,对黄土边坡在地震力作用下的安全性进行比较研究,对黄土边坡抗震设计具有一定的指导意义。

In consideration of the uncertain direction of seismic force during the earthquake,it is obviously deficient only to consider how the horizontal seismic forces influence the loess slope.By use of the impact of the angle of earthquake,the seismic force is decomposed into the normal and tangential direction of the potential sliding surface,the seismic forces are calculated,and the security of the loess slopes under seismic force was compared,which has certain guiding significance to the seismic design of the loess slope.
