The authors introduce the control and data acquisition system for the R500B biaxial (horizontal and vertical) shaker table of the IWHR (China Institute of Water Resources and Hydropower Research) Geotechnical Centrifuge. The control theory, the function of the software and the working procedures of the system are presented in this paper. This system has been successfully operated at 80 g centrifugal acceleration, and is needed to be improved to meet different requirements of experiments in the future.
