Abstract: The calculation of displacements and internal forces of the cantilever-retaining pile for foundation pit using biparameter method of foundation resistance is discussed. That is on the assumption that the foundation resistant coefficients varies nonlinearly with the depth according to biparameter theory; the strata are modeled by elastic foundation link elements and the soil-retaining piles are modeled by elastic beam elements. Based on the real measured data, the numerical simulation back-analysis of the cantilever- retaining pile for foundation pit indicates that the proper parameters of foundation resistance for practical design could be obtained through trial and adjustment. And the method is applied to practical analysis and design of the cantilever-retaining pile in Fuzhou. The result is satisfactory, so it could be referred by the design and the calculation of the cantilever-retaining piles for foundation pits.

Key words: biparameter method, cantilever-retaining pile, displacement and internal force, elastic foundation link element
