Construction Elements’ Research of Steel Box Girder Based on the 6 σ Quality Control Method
The steel box girder is widely used benefited from the high torsional and bending rgigidity, good entirety, light weight, better appearance and good stability. Using 6 quality control method, the problem diagnosis and quality control are made to the steel box girder’s making critical process such as assembly and jointing in the New Hi-Tech Zone of Xi'an’ s Arterial road 4# bridge , so as to meet the quality requirements.
