1. Discuss the relevance of the pore pressure ratio in the context of Bishop's method of slope stability analysis. Include in your discussion practical ways of obtaining values of the pore pressure ratio.

2. Describe the reason for wanting the pore pressure ratio, ru and the pore pressure coefficients A and B.

3. For a soil that has cohesive component to its strength, describe the mode of slope failure and the general approach used to determine the factor of safety for such a slope.

4. Describe three methods of obtaining pore pressure values. Describe all the terms in the expression for the pore pressure ratio, ru.

5. A railway cutting in London Clay was excavated in 1920, but now engineers are concerned about its stability. A senior engineer has suggested that the existing slope be analysed in terms of Bishop's rigorous method. Discuss the reasons why you think Bishop's rigorous method has been specified and explain all the relevant information that you would need to undertake the analysis.

6. Describe the reasons for using Bishop's method of analysis for a slope which was constructed 15 years ago.

7. Describe three methods of obtaining pore pressure values. Describe all the terms in the expression for the pore pressure ratio, ru.
