Method for controlling cumulative settlement of pile-supported subgrade strengthening pile
The invention discloses a method for controlling the cumulative settlement of a pile-supported subgrade strengthening pile. The method comprises the following steps: calculating a dynamic stress attenuating to the upside of a soil arch height by virtue of a Boussinesq's Equation; calculating according to the dynamic stress, a pile spacing and a share ratio of a load of a pile top to obtain the dynamic load above the pile top; calculating according to the weight of a subgrade filling, an upper load of a subgrade and the share ratio of the load of the pile top to obtain a static load above the pile top; calculating according to an ultimate bearing capacity of a pile tip and the static load above the pile top and the dynamic load above the pile top to obtain a cyclic load ratio and a static load ratio of a single pile above the pile top, namely, a thickness of the subgrade and the bearing capacity of the pile tip accord with a requirement in a case that the cyclic load ratio and the static load ratio of the single pile meet a certain condition so that the control for the cumulative settlement of the pile-supported subgrade strengthening pile is completed.
