摘　　要：为了确定顺向坡岩层走向与边坡走向夹角的上限值,进行了室内相似模拟试验,并统计了渝怀铁路沿线顺层滑坡的发育特征,作为室内试验的验证和补充.结果表明,边坡的稳定性随二者夹角的增大而增大;当夹角大于30°时,顺层滑坡的数量明显减少.因此,提出以30°作为顺向坡的上限.Similar simulation tests were made to determine the upper limit of angle between the strikes of slope and strata for a dip slope. Furthermore, the development characteristics of bedding-slips along the Chongqing-Huaihua railway from Fuling City to Longtan Town section were investigated to prove and complement the experimental result in lab. The research result shows that the stability of a dip slope enhances with the increase of the angle between the strikes of slope and strata, and bedding-shps occur seldom when the angle is over 30°. Therefore, from the experimental and statistical results the upper limit of the angle for a dip slope is 30°.
