Abstract:

The consideration of the nonlinear constitutive relations of soil for analyzing laterally loaded piles causes complex calculation or parameters difficult to obtain, which is inconvenient for engineering applications. The fundamental solutions of governing equation about the semiinfinite long pile under lateral loading were given based on mmethod of the linear elastic foundation and simplified elastoplastic constitutive relations of soil. The unified dimensionless analytical expressions of both the loadmaximun deflection relations and the loadmaximum moment relations under various loading cases were derived. The maximun deflection and the maximum moment can be expediently calculated by simple mathematical programs. The complex analytical solutions were simplified for more easily applying to engineering calculation. Results showed that the simplified equations calculated using a calculator agreed well with the exact solutions, and the largest error was less than 1%.
