  • BEHAVIOUR OF RETAINING WALLS UNDER DYNAMIC LOADS 
    Nandakumaran, P. (1973)
    The current practice of considering tha dynamic behaviour of retaining walls is to take into account an increase in the lateral earth pressure as calculated from the modified Coulomb formula. This has serious limitations. In ...
  • RESPONSE OF WELL FOUNDATIONS UNDER HORIZONTAL LOADS 
    Sharda, Satish Chandra (1975)
    Well foundations of bridges are subjected to vertical forces due to dead load of structure, live load of vehicles, buoyancy pressures and vertical inertial forces due to earth quakes. They are subjected to horizontal ...
