The gate-type steel-shuttering jumbo is key construction equipment for tunnel lining, which is usually designed for customization according to the shape and size of the tunnel. Aiming at the insufficiency of existing methods in the jumbo design, the CAD/CAE technology is introduced into the domains of the jumbo design. In this paper, the gate-type steel-shuttering jumbo for spillway lining in Xiluodu hydropower station is designed, and virtual assembly is established based on three-dimensional digital model using Pro/E software. The stress and strain of the jumbo under different working conditions are analyzed by ANSYS. The result of finite element analysis can be regarded as the basis of structure design and optimization of the jumbo, and can be used to verify the design feasibility at the same time.
