Abstract:

The linear control of segment prefabrication and assembly construction using the short linematching method runs through the entire construction process,with the focus on linear control during theprefabrication stage. However, the basis of linear control is measurement data,which inevitably leads tohuman errors. The measurement errors during the prefabrication stage will only be reflected in theassembly stage. Therefore, measures for adjusting errors during the assembly stage are also essential.This article takes the construction of the section beam erection of the Dongtouxia Cross Sea Bridge as abasis to introduce the method of linear control and error adjustment measures during the section beamassembly stage using short line matching method.
