The Ultimate Bearing Capacity of a Layered Foundation on Inclined Load

It is generally assumed that the sliding surface is composed of two inclined planes when we check the stability of a hydraulic engineeing structure and its layered foundation, especially the weak intercalated foundation at a slight slope angle. Now the author, having referred to the failure in the model test according to Coulomb's criterion, offers an approximate formula of the ultimate bearing capacity of a foundation on the assumption that the sliding surface consists of three segments.
