| Abstract: | According to the field test data of laterally loaded steel piles at home and abroad, an empirical formula for evaluating the modulus of subgrade reaction under static load in layered soil is proposed. The suggested formula takes account of not only non-linearity of K5 with the depth but also its variation with the load. It is shown that the computed bending moments along the pile shaft and the deflection at the pile top are consistent with the measured ones. |
