thanks
but i am just checking the sliding stability at some base section (not at the interface betwn wall and foundation soil/rock but at intermediate block joints)... in order to get FOS i want to calculate the friction resistance at that section and for that i need frictional coefficient (mue) ... some say take it 0.6 but it will be optimestic to adopt that as it is recommanded for fresh precast joints... another it is in saturated condition and silt deposition is also expected... anyone know any study carried out...
