PROBLEM TO BE SOLVED: To perform highly efficient execution work control by collecting and analyzing execution work data obtained at excavation propelling work in real time. SOLUTION: The execution work control system of a tunnel excavator is provided with data collecting means 30, 31, 35 and 41 to collect execution work data such as machine data, bedrock data and boring data obtained at excavation propelling work and a bedrock evaluating means 35 to evaluate properties of bedrock by performing operation on the basis of the collected data, and cutter torque, thrust, elongating speed, cutter rotating speed, the excavation propelling direction or the like are controlled by selecting a combition of operations of an excavation propelling mechanism according to properties of the evaluated bedrock. The execution work data to be collected can be obtained by an MG factor obtained by pressing a main gripper 14 against the bedrock side, an FG biting-in quantity obtained by making a front gripper 12 bite in the bed rock side or cargo loading testing data of an exclusive cargo loading testing device 58. |
