seasonal synusium

Based on WOA01 database, the permanent thermocline and seasonal thermocline are calculated in the Philippine Sea, and the regional and seasonal characteristics are investigated.

由于《海洋调查规范》规定的中国近海温跃层计算标准不适用于菲律宾海,本文通过统计分析得出了更合理的计算标准,并应用WOA01数据集对菲律宾海的温跃层进行了计算,得到了主温跃层和季节性跃层特征值的区域性分布和季节性变化。

In winter,seasonally frozen ground changes the dynamic properties of foundation soil and the predominant periods of soil sites,and then the seismic responses of pier on the seasonally frozen ground will be influenced.

季节性冻土层改变了地基土的动力特性和卓越周期,因而对桥墩的地震反应产生影响。
