Abstract

Abstract: Centrifuge modeling test was adopted to study the seawall engineering stability basing on the sea wall moving outwards practical engineering in Hangu district, Tianjin city. The modeling technology, modeling method and the operate method were presented in detail in the centrifuge modeling test which can provide a certain reference. Test results show that under the condition of 2 m scour depth, the toe and gear shift of thesea dike construction is small. One year later the vertical displacement were 58 mm and 28 mm seperately. The results show that the influence of display scour depth of the sea outside on the safety and stability is little.

Key words: hydraulic engineering, sand tube bag, centrifuge model test, slide stability

摘要： 针对天津市汉沽区海挡外移工程，采用离心机模型试验对海挡工程的安全稳定性进行了研究，介绍了离心机模型试验中所采用的模拟手段、模拟方式及操作方式。试验结果表明：在海挡工程外侧冲刷深度2 m条件下，海挡工程堤顶和堤脚位移较小，一年后竖向位移分别为58 mm和28 mm。研究表明：外侧冲深对海挡工程的安全稳定性影响较小。
