| Abstract: | Taking the cast-in-place support for line section of a long-span continuous rigid frame bridge side span as an example, the paper introduces the cast-in-place support platform calculation methods and basic checking, which ensures the strength and stiffness of support platform, foundation bearing capacity, bending, shear and compres- sive capacity can meet the design requirements; no uneven settlement is found in prepressure observation, and it can guarantee the stability of the bracket. |
