求翻译：在结构设计中，根据地质条件和码头功能先初步确定沉箱的外形尺寸和沉箱内填石高度，然后进行作用分析，按永久作用、可变作用、偶然作用列出码头荷载的标准值，在此基础上进行稳定性验算，根据验算结果对沉箱外形尺寸和沉箱内填石高度进行修改，并对沉箱前面板和底板进行了配筋计算和抗裂验算。是什么意思？

First preliminary structural design, according to the geological conditions and terminal capabilities determine the caisson Dimensions and caisson rock fill height, then the role of analysis, permanent role, variable role, the occasional role of listed pier load standard value, in this on the basis

In structure design in the, under geological conditions and terminal function first preliminary determines caisson of shape size and caisson within filled stone height, and for role analysis, by permanent role, and variable role, and accidentally role lists Terminal load contains of standard value,
