n the slope of surcharge isless than the natural slope but yet extends for some distance. Ran-kines graphic method applies particularly to the latter case. Let AB,Fig. 442, be the back of a wall 15 ft. high supporting a bank of earthwhich slopes at 1^ to 1, while the natural slope is 1 to 1. Put in… … r/y 443 produced cutting the semicircle in point G. From centre D with radiusDG cut DB in H. Then the horizontal thrust acting at one-third theheight will be T = iM;(BH)^. Let the earth in this case weigh 1 cwt.per cub. ft., then the thrust JK = 2857 cwt., which being at 5 ft.height gives an…
