Abstract

The mechanical properties of the joint can be described by the sandwich model or by contact model in FEM analysis.The ultimate bearing capacity of jointed rock foundations is analyzed by elastic-plastic FEM.The results show the ultimate bearing capacity of jointed rock foundations first deceases and then increases as the obliquity of the joint increases.The strength of the joint affects the ultimate bearing capacity of jointed rock foundations greatly unless the obliquity is too small or too large.The location of the joint also affects the ultimate bearing capacity of jointed rock foundations.In engineering practice, the effects of joint should be considered carefully.
