Study on Main Tunneling Parameters of Earth Pressure Balanced Shield Machine in Karst Area
In order to study the control problem of main tunneling parameters of earth pressure balanced shield machine in Karst area,based on the shield construction project between Sifanghe Station and Zaojiaojing Station in the first phase of Guiy-ang Urban Rail Transit Line 3,the main tunneling parameters such as total thrust,cutter head torque,tunnelling speed and earth bin pressure of the shield machine were statistically analyzed,and the correlation and influencing factors of tunneling pa-rameters were studied using mathematical statistics method.The results show that the control values of main tunneling parame-ters of earth pressure balanced shield machine accord with the normal distribution law in Karst area.Affected by special geo-logical conditions,the correlation between parameters is weak.The research results can provide some reference for other simi-lar tunnel projects.
