    Methods of Calculating Acceptable

    Deflection at Working Load;

    1.Modulus of Subgrade Reaction Approach (Reese

    and Matlock, 1956):

    2.Elastic Approach (Poulos, 191a and b!"

    # $t is relati%el& si'ple

    # $t can incorporate factors such as

    nonlinearit&, %ariation of subgrade reaction

    ith depth, and la&ered s&ste's.
