| 摘 要： | 以长江口深水航道治理二期工程为依托，进行基床基础防波堤的动力软化判别标准的研究，分析在波浪作用下3个不同沉降量的典型断面下卧地基土的自重应力、附加静应力、波浪作用的附加动应力分布间的关系，初步得出该地区软粘土可能出现动力软化现象的判别标准。

| Abstract: | Taking the example of Yangtze River Estuary Improvement Phase II Project,the study on a standard to distinguish the possibility of dynamic softening of soft soil in this area is given.Through the analysis on the distributing relationship among the deadweight stress,additional static stress and additional dynamic stress of the underlying soil for the three typical cross-sections with different settlements under the action of waves,the prelimi-nary standards distinguishing the dynamic softening of soft soil p... |
