大悬臂预应力混凝土盖梁的施工监测分析

摘要

Taking the large cantilever pre-stressed concrete cap beam construction of a viaduct as an example,from the structure modeling,pre-stressed steel beam system,stress monitoring and other aspects,introduced the construction monitoring technology of bridge structure engineer-ing,through the stress and displacement monitoring analysis of construction process,pointed out that the theory calculated value of large cantile-ver cap beam model in line with construction measured value.%以某高架桥大悬臂预应力混凝土盖梁施工为例，从结构建模、预应力钢束体系、应力监测等方面，介绍了桥梁结构工程的施工监测技术，通过对施工过程中应力和位移的监测分析，指出大悬臂盖梁模型的理论计算值与施工实测值比较吻合。
