| 摘 要： | 广珠城际铁路单箱双室简支箱梁,在架设过程中发现,受支座横桥向设置位置等因素影响,在架梁荷载作用下,梁端底板支座与腹板间部位出现裂缝,并沿梁体纵向有一定延伸。针对这一现象,采用梁端截面设半隔墙补强措施进行处理。通过实体梁静载及架梁梁端荷载试验与工程实践验证,加固效果良好。

| Abstract: | It is found during erection of the simply-supported double-cell box beam on Guangzhou-Zhuhai Intercity Railway that under the effect of loads,cracks occurred between the bottom base and web plate in beam-ends and extended along longitudinal direction caused by the erection position of bridge.For this phenomenon,semi-partition wall is set up in the section of beam-ends for reinforcing measures.Through solid beam static load and beam-end load test,the effect of reinforcement is verified very well in engineeri... |
