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,
