随机波浪荷载下海底地基的统一等效谐振荷载

本文根据南海砂样的试验资料和迈纳准则,通过归一化及随机振动分析,给出了在随机波浪荷载作用下,比较合理且适用性较广的统一等效谐振荷载。本文分别根据由实际波浪谱所确定的随机荷载历程及其相应的统一等效荷载,测定出各自相应的土的振动孔隙水压力,结果比较吻合,表明根据等效归一化方法求得的统一等效谐振荷载的可靠性与实用性。

Unified Equivalent Harmonic Loading on Seabed Soil Foundation for Random Ocean Wave Loading

According to laboratory tests and theoritical analysis a concept of unified equivalent harmonic wave loading is suggested and disscussed in this paper, which may be proved to be more reasonable and widely applicable in offshore foundation engineering. A proving test has also been completed, in which the random wave loading and the corresponding unified equivalent loading were respectively applied on soil samples. The test results show that the equivalent effect is satisfactory.
