Abstract

The seepage velocity along the outflow face of a layered slope is examined. The layers subdivide the slope into thin confined aquifers, which carry the groundwater to the outflow face. It is shown that a singularity, a possible cause for piping, occurs if the gradient in the aquifer is larger than the slope of the embankment. The corresponding groundwater flow problem is solved analytically. Expressions for the normal component of the discharge function along the outflow face are presented. This component is reproduced graphically for a slope of 30SUP and the corresponding flow net is shown. (A)
