Abstract:In order to control the earth pressure balance more accurately and efficiently,a new modeling method for control the earth pressure in pressure chamber was proposed.Based on the in-site construction data eliminating the noise by using the wavelet threshold denoising method,an earth pressure field model of the pressure chamber was established by using least square method;on this basis,by analysing the relationship between tunneling control parameters and the earth pressure in chamber and the impact factor of the earth pressure states change,the EPB control model was established which takes the equivalent earth pressure as control target.The fuzzy adaptive PID controller was designed and the EPB control system was constructed.Finally,the simulations were given to illustrate the effectiveness of the earth pressure control model,which lay a foundation for the shield EPB control.
