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。
In this paper, based on the experimental data of South China Sea sand samples and the Miner’s criterion, the normalized and random vibration analysis is used to give a uniform equivalent resonant load that is reasonable and applicable under random wave loads. In this paper, according to the stochastic load history determined by the actual wave spectrum and its corresponding uniform equivalent load, the vibration pore water pressures of the corresponding soils are determined. The results are consistent, indicating the unity obtained by the equivalent normalization method. Reliability and practicality of equivalent resonant loads.
