波浪作用下海洋浅层软土弱化与场地稳定性

Degradation and stability of soft soil site under wave loading

本文研究了海洋软土的循环弱化粘弹性本构关系，进而把它与波浪、水、土多层计算模型相结合，提出一种定量分析波浪作用下海洋软土场地稳定性的方法．由于它考虑了软土的循环弱化而导致的非线性粘弹性参数的变化，使分析结果能比较真实地反映波浪作用下海洋软土层的变化过程．

In this paper the visco\|elasticity constitution relationship of cyclic degradation describing offshore soft clay behaviors is studied.A method for quantitatively analyzing the stability of offshore soft soil sites under wave loading is developed by combining the relationship with water\|mud multi\|layer interface model.Since the variation of nonlinear visco\|elasticity parameters due to cyclic degradation of soft clay can be considered,the analytic results can reflect the changing process of soft clay under wave loading.
