【正文】 s. In the box girder construction, the capacity of the bridge bearing in the construction is very large. In order to support the security， economic of construction， the erection of the scaffold is necessary and reasonable , so the load of support is extremely important. Take the construction of Xiujiang River Bridge for example, this concrete continuous beam bridge construction with Full Space Support design. Choose to use science and technology economy, reasonable and safe method of stent support programs load analysis, stability checking and stent design of prepress identify the most unfavorable Full Support the forces, and check its stiffness and stability. Following checking the vertical and horizontal Ibeam39。s bending normal stress, bearing shear stress, deflection and stiffness. Learn about other construction techniques and construction process, specifically related to technical specifications. Attention to the question during the construction process may arise. Keywords: full space support box girder load analyse
