| 摘 要： | 地震过程中,最大峰值加速度是一个随机量,不宜作为地震动特性的标志,因此,利用均方根加速度,计算相应的地震力,然后根据正弦函数曲线把地震力加载在不同土层的黄土边坡中.对黄土边坡在地震力作用下的安全性进行比较研究,为黄土边坡抗震设计提供参考依据.

| Abstract: | Considering that during the earthquake,the maximum peak of acceleration changing in the process is a random quantity,which can’t be regarded as a sign of dynamic motion characteristics.Therefore,in this paper,the root mean square acceleration is employed to calculate the corresponding seismic forces.Then according to the sine curve,seismic forces are loaded on the different layers of slope of loess slope.Giving a comparative study on the safety of the loess slope under the force of the earthquake provides reference for the design of loess slope against earthquake. |
