Seismic Response Analysis of Deeply Embedded Large Diameter Cylindrical Structure

Nonlinear numerical model of Large Diameter Cylindrical Structure and Soil Interaction is constructed. The Dynamic Response of Large Diameter Cylindrical Structure under measured seismic wave is studied. The following conclusions can be obtained: the displacement change of cylinder at the free end is the biggest, the stress of cylinder at the bottom is the biggest and has large circumferential moment, the There is a rotating point between the structural midpoint and the bottom, the structure and the soil inside cylinder rotates around the rotating point. There is a certain lag in the displacement curve compared to the curve of seismic wave acceleration, the peak time-point of speed response curve is slightly earlier than that of displacement response curve, but the shape of the two curves is similar. Results can provide evidence for the design of deeply embedded large diameter cylinder.
