后张法预应力混凝土简支梁桥的恒载挠度分析

Analysis of dead load deflection of post-tensioned pre-stressed concrete simple-supported beam bridge

结合工程实例,使用桥梁专用软件分析了预制简支梁的挠度影响因素,并从理论上建立模型,测试了混凝土养护龄期、预制主梁的存梁期及恒载和活载之比等对板梁变形的影响,为设计施工提供了一些依据。

Combined with practical engineering, the author analyzes the factors influenced the deflection of prefabricated simple-supported beam with bridge proprietary software, builds model theoretically, tests the influences of concrete maintenance stadium, storage period of prefabricated main beam, and ratio between dead load and live load, which to offer some references for the design and construction.
