Method for predicting bearing capacity of single-disc branch pile
The invention generally relates to the technical field of squeezed branch piles, in particular to a method for predicting the bearing capacity of a single-disc branch pile. The method comprises the steps that cohesive force, the internal friction angle of foundation soil, the weight of a soil body, the width of a disc ring, the section area of a pile end, the embedding depth of a disc, the diameter of the disc and the diameter of a pile are obtained; according to the cohesive force, the internal friction angle of the foundation soil, the weight of the soil body, the width of the disc ring and the embedding depth of the disc, the ultimate bearing capacity of the soil body is calculated based on the ultimate equilibrium theory; calculating the projection area of the disc according to the disc diameter and the pile diameter; calculating the bearing capacity of the disc according to the ultimate bearing capacity of the soil body and the projected area of the disc, wherein the bearing capacity of the disc is in positive correlation with the ultimate bearing capacity of the soil body and the projected area of the disc; and according to the section area of the pile end, the ultimate bearing capacity of the soil body and the bearing capacity of the disc, the bearing capacity of the single-disc branch disc pile is calculated by combining the calculation principle of the bearing capacity of a common cast-in-place pile. The bearing capacity of the disk is considered, and the accuracy of the prediction result is higher.
