吸力锚土塞在粉质粘土中形成的模型试验研究

Model tests on soil plug formation in suction anchor for silty clay

摘要: 介绍在室内粉质粘土土槽中进行吸力锚土塞形成试验 ,给出了部分试验结果。通过模拟海上吸力锚沉放过程 ,研究土塞形成和发展的规律及模型沉放过程中压力差、沉放速度等因素对土塞形成产生的影响。并对一些试验现象和结果进行了初步分析 ,得出了一些结论。

Abstract: A series of model tests designed to present the formation of soil plugs in the process of penetration of suction anchors in silty clay is introduced,and some test results are put forward.By simulating the practical situation of penetration of suction anchors in sea,the relations between the height of soil plug and the factors such as pressure, penetration speed of anchor models, etc are studied.Some phenomena and results of tests are analyzed and some valuable conclusions are primarily obtained in this paper.
