6. A group of nine friction piles of 200 mm diameter spaced at 0.5 m transfer a load of 400 kN into a 10 m thick clay layer with sand below. It penetrates to a depth of 6 m in the clay layer. Estimate the probable settlement of the pile group. Assuming water table is at ground level. Take water content = 39%, G = 2.7 and γ_sat = 20 kN/m³.
7. a) Discuss in detail different types of bridge maintenance.
   b) Write a short note on behavior of bridges under dynamic loads.
8. Explain briefly with suitable sketches the component parts and structural actions of truss bridges, cable-stayed bridges and suspension bridges.
