大悬臂预应力盖梁设计与计算

Design and Computation of Long Cantilever Pre-stressed Bent Cap

针对城市高架桥项目中的大悬臂预应力盖梁,以实际工程中的典型桥墩为研究对象,通过建立MIDAS计算模型,分别对施工过程及桥梁运营中盖梁受力进行分析,对预应力盖梁尺寸及计算各项参数取值进行研究,为大悬臂预应力盖梁的设计与应用提供借鉴。

Aiming at the long cantilever pre-stressed bent cap in the urban viaduct project, taking the typical bridge pier of engineering case as the study subject, and through the establishment of MIDAS computation mode, the article separately analyzes the stresses of bent caps in the construction process and bridge operation, and studies the dimension of pre-stressed bent caps and the computation of various parameter values, which can be referred for the design and application of long cantilever pre-stressed bent cap.
