In consideration of these complicated factors, Duncan—Chang model is used for the soil in this paper, and the deep excavation is modeled by using the method of coupling of multiple finite elements such that calculation results approach to actual condition. In addition, based on the theory of increment method, dynamic simulation using the finite element methods is investigated for the deep excavation.

Around the topic, the weak points of the traditional platform is analyzed first, such as complex arithmetic, long calculating time, high needs of hardware and so on. A real time control method based on virtual simulation is suggested to separate the complex positive/negative calculation of space kinematic and real time motion control. And a"3-2-1"type 6DOF platform is designed with the reference of the MAST (Multi-Axis Shaking Table) of MTS. The kinematic and dynamic calculation of the platform is finished. According to the calculating result, the control system of the"3-2-1"type 6DOF platform including 6 linear servo electric cylinders is designed and constructed. And the professional software Pro/E is used to do the 3D model and 6DOF motion simulation of the platform. The motion curves of the pistons of the 6 cylinders are exported with the simulation. At last the control software is programmed with Microsoft Visual Basic 6.0 and realizes the functions with the commands of GE series motion controllers. When loading the motion curves exported with the simulation, every cylinder can follow the curve very well and the platform realizes the hoped 6DOF motion.
