| 摘 要： | 针对某工程开孔沉箱消浪室盖板顶托力问题,采用现场观测研究手段,对顶托力与潮位进行观测,总结潮位和顶托力分布特点,分析顶托力在单日、短时长和整个观测期间的规律以及顶托力过程和历时,对比盖板抬高0. 5 m后顶托力变化。结果表明:顶托力增长过程与潮位升高过程一致,盖板受力为潮位静水压力和波浪动水压力共同作用的结果,不同仓之间的受力表现为后仓中仓前仓,若盖板抬高0. 5 m,盖板受力状态将得到明显改善,沉箱盖板底高程对顶托力起着决定作用。

| Abstract: | Field observation is carried out to measure the wave uplift load of cover plate in perforated caisson.The processes of tidal level and uplift load are analyzed by a single day,a short period and the whole period,including the load process and time duration.The statistical result of load process and time duration of elevation up by 0.5 m is compared with the original elevation.It can be found that the rising process of uplift load grows in step with the tidal level.The uplift load is induced together by the tidal level and wave action.The load order for different bins from large to small is the back,middle and front.The uplift load would be obviously improved if the elevation of cover plate is raised by 0.5 m.The elevation plays a decisive role on the state of uplift load for cover plate in perforated caisson. |
