ABSTRACT
BISHOP'S SIMPLIFIED METHOD OF SLICES Bishop's method of slices (1955) is useful if a slope consists of several types of soil with different values of e and </J and if the pore pressures u in the slope are known or can be estimated. The method of analysis is as follows:
Figure 10.23 gives a section of an earth dam having a sloping surface AB. ADC is an assumed trial circular failure surface with its center at O. The soil mass above the failure surface is divided into a number of slices. The forces acting on each slice are evaluated from limit equilibrium of the slices. The equilibrium of the entire mass is determined by summation of the forces on each of the slices.
