Abstract A silty seabed can be destabilized in two ways under wave loading: by liquefaction or shear failure. In this paper, the wave-induced initial failure mode of a silty seabed under different consolidation conditions is studied using flume experiments. Through a comparison of the pore water pressure, initial failure, and liquefaction development patterns in a relatively soft and dense seabed, it is found that liquefaction is responsible for the initial failure of the soft seabed, while shear failure is responsible for the initial failure of the dense seabed. Liquefaction progresses from the surface and gradually downward in the soft seabed, but it propagates from the interface where the shear failure occurs in the dense seabed.

粉质海床初始波浪诱发破坏：液化或剪切破坏

摘要 粉质海床在波浪载荷作用下会以两种方式失稳：液化或剪切破坏。本文通过水槽实验研究了不同固结条件下粉质海床的波浪诱导初始破坏模式。通过比较相对松软致密海床的孔隙水压力、初始破坏和液化发展模式，发现液化是软海床初始破坏的原因，而剪切破坏是软海床初始破坏的原因。密密麻麻的海床。液化从表层开始，在软海床中逐渐向下，但在密实海床发生剪切破坏的界面处传播。
