| 摘 要： | 基于笔者所建立的随机波浪荷载激起建筑物振动而作用于海底地基上的统一等效荷载，以及分析判断振动荷载下土体中振动孔隙水压力生长程度的能量法，研究、探讨了重力式海洋建筑物的振动导致地基中振动孔隙水压力的发展和地基的整体稳定性。具体算例表明这种方法用于分析海岸、海洋建筑物地基的动态问题比较合理、可行，且便于工程应用。

| Abstract: | Based on unified equivalent harmonic loading on seabed soil foundation and energy approachsuggested by the authors,the development of dynamic water pore pressure and stability of soilfoundation for the vibration of nearshore/offshore gravity structure foundations excited byrandom wave loading are analysed. It may be seen that the dynamic problems of nearshore/offshore gravity structure soil foundations studied in this way is more reasonable and convenient. |
