Upper Lim it ofAngle between Strikes of Slope and Strata for Dip Slope

Similar simulation testsweremade to determine the upper limitofangle between the strikes of slope and strata for a dip slope. Furthermore, the developmentcharacteristics ofbedding-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 enhanceswith the increase of the angle between the strikes ofslope and strata, and bedding-slips occur seldom when the angle is over 30°. Therefore, from the experimental and statistical results the upper limitof the angle for a dip slope is 30°.
