Design of Drilled Shafts for Slope Stabilization
Mechanical and Civil Engineering
A design method for using the drilled shafts to stabilize an unstable slope is presented in this paper. The method is based on the concept that the presence of drilled shafts in a slope reduces the driving forces on the down slope side of the drilled shafts due to the soil arching by which the earth pressure was transferred to the drilled shafts. The presented design procedure allows for optimization of the drilled shafts size, shaft location, shaft fixity (the necessary rock-socket length), and the spacing between the drilled shafts for a given unstable slope with known slip surface to achieve the desired target FS of the slope/drilled shafts system.
