Abstract

The invention discloses a method for determining the accurate cutting amount of a special-shaped steel structure closure section. The method comprises the following steps of acquiring the relevant data of the installed segments before closure and the closure segment characteristic coordinate data, based on the segment corner point ridge fitting of the discrete points, constructing a cutting amount mathematical model, obtaining an optimal posture through a closure segment space state optimization target and a constraint function, and solving a cutting amount. By means of the method, the cutting amount of the irregular closure section can be accurately obtained, it can be guaranteed that the special-shaped steel structure is smoothly closed, then the construction efficiency of a project is improved, and the data support is provided for improving the project quality.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for determining the precise fitting and cutting amount of closing sections of special-shaped steel structures. Background technique [0002] Closing is an important link in the transformation of the structural system of the bridge. Affected by factors such as the difficulty in accurately simulating the force and deformation behavior of the system and the existence of errors in construction control, there is a certain deviation between the geometric shape and the target state when the closing mouth is formed. The gap is far away from the temperature displacement zero point of each structural system, and the shape of the gap is greatly affected by the ambient temperature and temperature field, making the gap a key and difficult point in the quality control of the bridge construction process, especially for the steel prefabricated in the factory. In terms of struc...
