Based on hardware redundancy con-trol technology to carry out the control loop process analysis, key control algorithm design of the earth pressure balance( EPB) shield synchronous grouting control system software, and control conditions of synchronous grouting system relevance and control loop flow analysis. Through the indoor experiment, the above design is verified and summarized. The application prospect of the hardware redundancy control technology in the automatic control system of shield machine is discussed.
