【摘要】：桶式基礎(chǔ)防波堤既能創(chuàng)造良好的港內(nèi)穩(wěn)泊環(huán)境,又能減輕港池內(nèi)航道的淤積。為了深入研究新型桶式結(jié)構(gòu)在運營期的工作特性,通過自主開發(fā)的自動化監(jiān)測系統(tǒng)對該結(jié)構(gòu)進行了原位試驗。試驗結(jié)果分析表明:在整個觀測周期內(nèi),土壓力和孔隙水壓力變化符合規(guī)律,總應力隨著時間的推移呈現(xiàn)周期性變化,但是振幅并沒有太大變化;有效應力隨著時間的推移有增高的趨勢,超靜孔隙水壓力逐漸消散,地基土體緩慢固結(jié)。
[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.
