The cases above provided information which was expanded by computer <br />analysis to determine the force balance for trial designs. This resulted in a guideline <br />being developed which designated minimum rock and grout thicknesses. Also, the <br />basis of the analysis is explained so that other engineers can use or modify this <br />approach in their work. <br />
