彭湖高速特大桥现浇支架的受力计算及稳定性分析

Force Calculation and Stability Analysis of Cast-in-Place Support for Penghu High Speed Bridge

支架现浇法施工是指将桥梁主体结构在现场搭设完备的支架上制作成形,待其具有一定的承载能力后,再施工上部其他附属结构的一种施工方法。该工法具有技术成熟,运用广泛等特点。论文以彭湖高速特大桥为例,介绍该类支架现浇过程中的受力计算及稳定性分析。

The construction of support cast-in-place method refers to a construction method in which the main structure of the bridge is formed on a complete support set up on the spot, and after it has the corresponding bearing capacity, the upper subsidiary structure is set up.The method has the characteristics of mature technology and wide application. Taking Penghu High Speed Bridge as an example, this paper introduces the force calculation and stability analysis in the cast-in-place process of this kind of support.
