摘要
海洋粉土在波浪作用下容易发生破坏。阐述了用海洋粉土铺设水槽底床进行波浪水槽试验,观察了粉土的破坏过程,根据对土体取样测试结果分析表明在波浪循环振动荷载下,土体破坏部分物理力学特性有所提高。同时对粉土在波浪作用下的破坏机制进行了探讨。
The unconsolidated silt failed easily under the action of wave loading. A flume test was conducted with silt obtained from seabed, the disruptive phenomenon was observed. Based on the results of measurements of silt, we found that the physic-mechanical properties of unconsolidated silt were improved partly under the periodic wave loading. At the same time, the disruptive mechanism was discussed.
