我国沿海许多地区的表层土质为含水量高、孔隙比大的软粘土，在海浪的往复荷载作用下，由于土层被扰动，强度进一步降低，将使位于该土层上的构筑物发生很大附加沉降甚至失稳破坏。虽然国内外已开展了对软粘土软化问题的研究，但尚未获得较成熟的工程实用方法，本文提出一种较简便的估算分析方法，并对计算结果通过离心模型试验进行了验证，其结果对于工程设计人员是很有意义的。
In many parts of China’s coastal areas, the topsoil is a soft clay with high water content and large void ratio. Due to the disturbance of the soil layer under the cyclic loading of the waves, the strength of the soft clay is further reduced, which will greatly add to the structure on the soil layer Settlement or even destabilization damage. Although the research on soft clay softening has been carried out at home and abroad, more mature and practical engineering methods have not yet been obtained. A simpler method of estimating and analyzing is proposed in this paper. The results of the calculation are verified by centrifugal model tests. Engineering staff is very meaningful.
