Q6) Give comparison of Rankine's and Coulomb's theory.
Q7) Derive bosussinesq equation for a point load.
Q8) Define pile foundation. Discuss about the types of pile and their functions.
Q9) What are the different methods of soil stabilization? Explain with neat sketches.
NOTE : Disclosure of identity by writing mobile number or making passing request on any
page of Answer sheet will lead to UMC case against the Student.
