AI Technical Summary

Technical Problem

In existing technologies, the design of circumferential reinforcement for reinforced concrete pipe jacking is cumbersome and prone to errors. It cannot simultaneously meet the requirements of ultimate limit state design and serviceability limit state design, making it difficult to guarantee the compliance and reliability of the design results. Furthermore, general design software lacks a dedicated module for pipe jacking, and reinforcement parameters cannot be automatically retrieved and optimally matched.

Method used

A circular reinforced concrete jacking pipe reinforcement method based on iterative algorithm is adopted. By constructing a standard database, inputting the jacking pipe itself and the stratum parameters, calculating internal forces, iterating the diameter and pitch of the reinforcing bars, and automatically selecting reinforcement schemes that meet the requirements of bearing capacity verification and crack verification, the system modules are combined to perform parameter input, verification and calculation.

Benefits of technology

It improves design efficiency and compliance, reduces human calculation errors, ensures that the reinforcement scheme is consistent with the actual engineering conditions, avoids structural cracking and damage, takes into account both economy and construction feasibility, and conforms to the trend of refined design of reinforced concrete structures.

Abstract

The application discloses a circular reinforced concrete pipe jacking reinforcement method and system based on an iterative algorithm, and steps are as follows: 1, constructing a standard database; 2, pipe jacking self parameter input; 3, stratum related parameter input and verification, determining stratum load basis, providing accurate soil load data for internal force calculation; 4, pipe jacking internal force calculation, calculating pipe jacking ring section internal force according to pipe jacking self parameter and soil load data; 5, ring reinforcement calculation, taking diameter and screw pitch reinforcement parameter as iterative variable, automatically performing reinforcement parameter iteration according to the searching rule of'small diameter and large screw pitch', and finally screening out the reinforcement scheme of steel bar diameter and corresponding screw pitch which simultaneously satisfies bearing capacity checking and crack checking requirements. The system comprises a database module, a pipe design parameter module, a soil parameter module, an internal force calculation module and a reinforcement calculation module. The application realizes pipe jacking reinforcement with consideration of economy and rationality, and improves design efficiency, compliance and rationality.
