Abstract

The mathematical model of earth pressure balance system of shield machine is proposed that is based on the mass balance principal in chamber of shield and Hook law of soil material. The state equation of the system is used to depict the relationship between earth pressure in chamber of shield and angular velocity of screw conveyor. The differential form of mathematical model of earth pressure system is derived. In order to determine model parameters of soil pressure balance system of shield, the genetic algorithm is used and developed. Based on the measured data in laboratory experiments, the model parameters are estimated. The investigation shows that the predicted soil pressure in chamber of shield agree well with observed ones. The effectiveness of proposed parameter estimation procedure is validated by experimental investigations in laboratory.
