FM 5-410 CHAPTER 10 Slope Stabilization This chapter pertains to the design of earth The following paragraphs describe geologic slopes as it relates to road construction. It features that have a significant effect on slope particularly concerns slope stability and stability and the techniques that may be used which slopes should be used under average to identify them: conditions in cuts and embankments. Some of the subjects covered are geologic features Faults that affect slope stability, soil mechanics, in- The geologic uplift that accompanies moun- dicators of unstable slopes, types of slope tain building is evident in the mountainous failures, and slope stabilization. regions throughout the world.

These fractures may extend for personnel engaged in road-building activities great distances both laterally and vertically and are known as faults. Often the material be aware of the basic principles of slope stability. They must understand how these on one side of the fault is displaced vertically principles are applied to construct stable relative to the other side; sometimes igneous roads through various geologic materials material or serpentine may be intruded into faults. Faults are the focal point for stress with specific conditions of slope and soil. relief and for intrusion
