Control system for multi-hydraulic-cylinder tunnel simulated experiment platform

The invention discloses a control system for a tunnel simulated loading experiment platform and provides a control system for a multi-hydraulic-cylinder tunnel simulated experiment platform. According to the control system, hydraulic cylinders are grouped, and inlet and outlet oil paths of the hydraulic cylinders in each group are connected in parallel; force application of each group of hydraulic cylinders is controlled through reducing valves, and stretching out and drawing back of each group of hydraulic cylinders are controlled through reversing valves. The control system is applied to the multi-hydraulic-cylinder tunnel simulated experiment platform, and can solve the technical problems that the cost for configuration of servo valves, data collection cards and sensors is quite high and circuit structures are complex due to large structural size of the experiment platform, improve reliability and reduce the failure rate; the operating difficulty is reduced, and burden of operators is greatly reduced.
