  • SOIL STRENGTH PROPERTIES AND THEIR MEASUREMENT

    Another important feature in many stability problems is the rotation of the principal axes during loading or excavation and its effect on the shear strength of soft clays (Ladd and Foott 1974). The rotation of principal axes is shown in Figure 12-2. Before the excavation of the cut, the state of stress is represented by that shown in Figure 12

  • SLOPE FACE STABILIZATION FOR CRITICAL SLOPE SURFACES

    Failure can occur as slides, cracks and slope movement. Erosion control is intended to provide surface slope stability to protect the face of the slope and to strengthen portions of the slope below the surface by interlocking soil particles with a complex matrix of roots. There are differences between stabilization and erosion control.
