EXCAVATION CONTROL SYSTEM IN SHIELD TUNNELING METHOD

摘要

PROBLEM TO BE SOLVED: To facilitate construction control by providing a control target value determination means for computing control target value per ring and a jack pattern control means for controlling a shield propulsion machine using the control target value. SOLUTION: A control target value determination program 100 calculates the inclination of a segment needed for correcting a route based on survey data of a shield propulsion machine 200 and existing segments and planning route data of a planning linear data file 130. And the program 100 produces a corrected segment plan based on directions and tail clearances of the machine 200 and segment data of a planning segment file 120. And the program 100 calculates control target values, as target stroke values for every ring, based on corrected segment plan. Further, a jack pattern control program 150 controls the machine 200 based on control target values of a control target value file 140 to execute excavation for ring.
