互通匝道桥现浇连续箱梁满堂支架设计与计算

The Design and Calculation of Cast-in-place Continuous Box Beam Full Framing for Interchange Ramp Bridge

根据岢临高速公路互通立交连续箱梁施工实践,介绍了现浇连续箱梁满堂支架的设计,并对支架底模、横梁、纵梁强度、立杆受力、刚度和稳定性及地基承载力进行验算,并对预压过程进行观测,施工完成后各项指标均满足规范要求,较好地指导了本桥施工。

According to the continuous box beam construction practice of Kelin Expressway interchange, this paper introduced the design of the cast-in-place continuous box beam full framing, and checked the bracket bottom mold, beam, longitudinal beam intensity, pole force, stiffness and stability and bearing capacity of foundation. It also observed the preloading process.
