This work designs a novel hydraulic-walking incremental launching equipment. The working principle of the equipment is proposed. Considering that the contact in incremental launching construction is a typical elastic contact problem, and changes in contact state will directly affect the stability of the incremental launching, this work proposes the equilibrium equations of computational contact mechanics and numerical analysis method for the incremental launching equipment through analyzing the working process of the equipments. The proposed model and method are applied in the analysis of typical working conditions of the incremental launching of Donghua Bridge. The structural characteristics in the construction process are analyzed and discussed. The analysis results show that the strength and stability of the steel box girder can meet the construction requirements. The incremental launching of Donghua Bridge was completed successfully. The proposed model and method can be used to predict and analyze the structural performance in incremental launching construction as well as provide theoretical reference and analysis method for similar constructions.
