This application discloses a method, apparatus, storage medium, and electronic device for determining the location of rebar breakpoints. The method includes determining corresponding target segment intervals based on the distances between multiple adjacent supports with a connection relationship in an engineering drawing; determining a current breakpoint in the engineering drawing that matches at least one target rebar object based on a first reference length of a first reference rebar object; repeating the following steps until the remaining length of the target rebar object is less than the first reference length: if the current breakpoint is within the target segment interval, determining the next current breakpoint based on the first reference length, using the current breakpoint position as the starting point; if the current breakpoint is outside the target segment interval, adjusting the current breakpoint position to within the target segment interval that meets the segment length condition, and determining the next current breakpoint based on the first reference length. This application solves the technical problem of low efficiency in determining the location of rebar breakpoints in related technologies.

This invention relates to a design and construction control method for prefabricated composite supports considering eccentricity, comprising: 1. Pre-embedding strain sensors in the middle and ends of segments to ensure that the deviation between the centroid of the steel frame and the centroid of the concrete in each segment is ≤L / 5000, where L is the segment length; measuring and recording the measured value e0 of the initial centroid eccentricity before leaving the factory; 2. Determining the axial force distribution coefficient of the steel frame based on the stiffness ratio; calculating the additional bending moment Madd caused by centroid eccentricity under axial pressure P using e0; calculating the ultimate bearing capacity Pmax based on Madd and P; 3. Collecting the strain of the steel frame and concrete in layers during foundation pit excavation, and measuring the horizontal displacement Δ of the diaphragm wall at the support elevation; calculating the additional bending moment M during construction based on Δ. Δ M Δ The total bending moment M is obtained by superimposing Madd, and the crack width w is calculated from M; the actual eccentricity e during the construction stage is calculated from the measured strain. a , will e a Compare with e0 and check the cross-sectional stress; IV. Take control measures as appropriate.

This invention discloses a method for processing giant bridge tower piers, comprising the following steps: a pre-processing stage, establishing a three-dimensional solid BIM model, determining the dimensional parameters and assembly relationships of each component, and generating a visual processing flowchart and parameter table; a longitudinal rib segmentation stage, determining the segment length of the longitudinal ribs based on the spacing of the transverse diaphragms, ensuring that the length of a single longitudinal rib segment does not exceed four transverse diaphragm spacings and does not exceed 4m; a longitudinal rib curling stage, simulating the theoretical height loss of the longitudinal ribs after segmentation using the BIM model, and performing curling processing on longitudinal ribs with a height loss greater than 100mm after segmentation; a general assembly jig stage; an assembly stage, dividing the giant tower pier into multiple layers, assembling the giant tower pier symmetrically from the inside out; and a multi-segment pre-assembly and positioning matching stage. This invention enables high-precision, high-efficiency, and high-quality processing of tower pier components.
