Questions and Problems

9.1 Explain the method of slices for stability analysis of slopes. How can steady seepage be ac-

counted for in this method? (S.V.U.—Four-year B.Tech. April, 1983 B.E., (R.R.)—Feb., 1976)

9.2 Write the expressions for the factor of safety using the method of slices when the slope of a

homogeneous earth dam is dry and when fully submerged. Assume the soil to possess both cohe-

sion and friction. (S.V.U.—B.Tech. (Part-time)—May, 1983)

9.3 Write brief critical notes on ‘Taylor’s Stability Number’.

(S.V.U.—B.Tech. (Part-time)—Sep., 1982, April, ’82,

June, ‘81; Four-year B.Tech—June, 1982)

9.4 Write critical notes on the friction circle method of analysing the stability of slopes.

(S.V.U.—B.Tech. (Part-time)—April, 1982, B.E.,(R.R.)—Sept.,

1978, Nov., 1972, Dec., ‘71, Dec., ‘70, May, 1970)

9.5 Give the step by step procedure for analysing the stability of the upstream slope of an earth dam

by the Swedish method of slices. Bring out the effect of sudden drawdown on the stability of the

slope. (S.V.U.—Four-year B.Tech.—June, 1982)

9.6 (a) Describe a suitable method of stability analysis of slopes in (i) purely saturated cohesive soil,

(ii) cohesionless sand.

(b) Under what conditions (i) a base failure and (ii) a toe failure are expected? Explain.

(c) Critically discuss the basic assumptions made in the stability analysis of slopes.
