METHOD FOR DETERMINING THE ORIENTATION AND POSITION OF THE BASE MACHINE OF A TUNNEL BORING MACHINE, WHICH BASE MACHINE BEARS THE WORKING HEAD

摘要

The invention relates to a method for determining the orientation and position of the base machine (23, 123) of a tunnel boring machine (100, 200), which base machine bears the working head (21, 121), wherein the position of at least one intermediate measurement point (1, 1', 1'', 1''', 101, 101', 101'', 101''') arranged on the tunnel boring machine is measured in relation to a stationary reference point (2, 102) and the position of at least one main measurement point (3, 3', 103) is measured in relation to the intermediate measurement point.
