【摘要】：桶式基础防波堤既能创造良好的港内稳泊环境,又能减轻港池内航道的淤积。为了深入研究新型桶式结构在运营期的工作特性,通过自主开发的自动化监测系统对该结构进行了原位试验。试验结果分析表明:在整个观测周期内,土压力和孔隙水压力变化符合规律,总应力随着时间的推移呈现周期性变化,但是振幅并没有太大变化;有效应力随着时间的推移有增高的趋势,超静孔隙水压力逐渐消散,地基土体缓慢固结。
[Abstract]:The bucket foundation breakwater can not only create a good stability environment in the harbor, but also reduce the siltation of the waterway in the harbor pool.In order to study the working characteristics of the new type bucket structure during the operation period, an in-situ test was carried out through the self-developed automatic monitoring system.The experimental results show that the variation of soil pressure and pore water pressure accords with the law during the whole observation period, and the total stress changes periodically with time, but the amplitude does not change greatly.The effective stress increases with time, the excess pore water pressure dissipates gradually, and the foundation soil is slowly consolidated.
