Internal force calculation method for single inverted stepped variable-cross-section pile
An internal force calculation method for a single inverted stepped variable-cross-section pile comprises the steps that the transverse displacement and turn angle of the single inverted stepped variable-cross-section pile on the ground or the maximum washing line position under the unit shear force action are calculated; the transverse displacement and turn angle of the single inverted stepped variable-cross-section pile on the ground or the maximum washing line position under the unit bending moment action are calculated; the transverse displacement and turn angle of the single inverted stepped variable-cross-section pile on the ground or the maximum washing line position under the shearing force Q0 and bending moment M0 action are calculated; the internal force of a pile body within the upper-section base pile diameter d1 is calculated; and the internal force of the pile body within the lower-section base pile diameter d2 is calculated. The internal force calculation method for the single inverted stepped variable-cross-section pile has the beneficial effects that the existing pile body internal force algorithm is popularized from equal-cross-section piles to inverted stepped variable-cross-section piles, and the internal force distribution of the variable-cross-section piles can be accurately worked out through the algorithm, so that bars are distributed for the variable-cross-section piles according to the internal force calculation result of the pile body, and the bearing capacity of the pile body is improved.
