Based on the theory of limit equilibrium, a new calculation module was presented to study the fracture mechanism of sloping ground, which could consider the effect of ascent of fill section at the back of slopes. To gain the mobilization factor of the fill section at the back of the sloping ground, the program was written with FORTRAN. In the calculation of the ultimate load capacity of sloping ground, the effects were considered, which included angle of internal friction of the sloping ground, underside slope angle, upside slope angle, relative distance from the edge of slopes and relative depth of footings. The mobilization factor of the fill section at the back of the sloping ground in different conditions was gained. Meanwhile, the load capacity factors and mobilization factor could be used in theory analysis and design of sloping ground.
