[0047] 1) Program implementation
[0048] This method requires the help of a special calculation program, the application of MATLAB7.0 or other computer languages can realize the computer programming of the above algorithm, the calculation steps are:
[0049] (1) Enter the measured data under various loads of each soil layer load test (p i , S i ), apply the least square method to hyperbolic fit the data;
[0050] (2) Output hyperbolic fitting parameters a, b;
[0051] (3) Calculate the additional stress distribution in the foundation under various loads;
[0052] (4) Select the convergence step of the additional stress correction coefficient β, and apply the foundation settlement formula (5) to iteratively solve the foundation settlement under all levels of load until the calculated settlement and load of the pressure plate under the final load (or other load) The actual settlement in the test is approximately equal, and the output β;
[0053] (5) Calculate the modified tangent...
