Abstract

In order to solve the problem of control difficulty of shield attitude and inhomogeneous consumption of cutting tools, the thrusting force ratio of hydraulic cylinder of shield tunneling in hardsoft fluctuated rocks of straight section and curved section of west extension line of Changsha Metro Line No. 2 is analyzed. The analytical results have been applied to actual practice and good effects have been achieved.

Key words： fluctuated rock; shield tunneling; attitude control; cutting tool consumption
