The main types of shield machines used recently in tunnel construction are earth pressure balance(EPB) shield tunneling and slurry shield tunneling. In order to reduce shield cutters wear,the parameter in shield construction advancing should be rational. This is fundamentally critical to ensure the shield to advance distantly in sandy cobble stratum. Sandy cobble is a typically unstable stratum and its mechanical properties are unfavorable for force transitivity and spread. Sandy cobble is also of unfavorable plasticity and fluidity,which will bring serious abrasion to shield cutters. By employing the latest dynamic supervisory gear,the abrasion of shield cutters used in shield tunnel section of Jiaomen Northern Load station to Beijing Southern station of Beijing metro line 4 was monitored;and the monitoring data were analyzed with the least square method. With abrasion coefficient as dependent variable,and advancement rate,total thrust,cutter-head rotation speed and cutter torque as independent variables,four regression expressions were established and eight regression graphs were drawn. Based on the regression expressions and graphs,the rational range of advancing parameters was proposed;and the fitting expression of abrasion of shield cutters to advancing distance was established,which may provide theoretical basis for reducing cutter abrasion in practical engineering,and for estimating the longest advancement distance in similar stratum. Based on the fitting expression of abrasion of shield cutters to tunnel advancing,the longest advancement distance is found to be 1.84 km in this stratum. The research conclusion is helpful for shield selection and engineering construction with similar geotechnical conditions.
