Influence of Aperture Ratio of Cutterhead of EPB Shield on Earth Pressure in the Chamber

Wang Hongxin(Shanghai Urban Construction Municipal Engineering(Group) Co.Ltd.,Shanghai 200065,China)  
Earth pressure in the chamber for EPB shield is not equal to earth pressure at the aperture of the cutterhead,resulting in the pressure difference which makes flowing of the soil on tunnel face into the chamber.Tests and site monitoring data indicate that the aperture ratio of cutterhead is one of important factors that affect the pressure difference.It is illustrated that under the same condition,a smaller aperture ratio will result in a bigger pressure difference in the chamber,on the contrary,a bigger aperture ratio will result in a smaller pressure difference.Based on the theory of fluid mechanics,this paper deduces a calculation formula of the pressure difference,which is verified by the site monitoring data and modified by the results of discrete element method.The research achievements make the quantitative analysis of the influence of aperture ratio on shield driving possible,which is significant for the management of earth pressure in the chamber and selecting of aperture ratio for EPB Shield.
