Zusammenfassung:PROBLEM TO BE SOLVED: To grasp a positional relationship with a rack mass after excavation, and a positional relationship with an installed segment, in a shield machine as a whole.SOLUTION: Shield machine coordinate information indicating a position of a shield machine is calculated on the basis of a distance and an angle from a reference point up to a measurement target in which a coordinate is sequentially measured from a well-known reference point, and which is defined in advance in the shield machine, and shield machine shape information indicating a shape of the shield machine. Excavation boundary coordinate information indicating a position of an excavation boundary of a tunnel is sequentially calculated on the basis of the shield machine coordinate information, and segment coordinate information indicating a position of a segment is calculated on the basis of a distance up to a segment from a measurement position which is sequentially measured from the measurement position which is defined in advance in the shield machine, a thickness and a length of the segment which are defined in advance, and the shield machine coordinate information. A positional relationship of the shield machine, the excavation boundary and the segment is sequentially displayed.SELECTED DRAWING: Figure 3 【課題】シールドマシンの全体において、掘削を行った後の地山との位置関係、及び設置したセグメントとの位置関係を把握することを可能とする。【解決手段】座標が既知の基準点から逐次計測される、当該基準点から前記シールドマシン内において予め定められる計測目標までの距離及び角度と、シールドマシンの形状を示すシールドマシン形状情報とに基づいて、シールドマシンの位置を示すシールドマシン座標情報を算出し、トンネルの掘削境界の位置を示す掘削境界座標情報を、シールドマシン座標情報に基づいて逐次算出し、シールドマシン内において予め定められる計測位置から逐次計測される、計測位置からセグメントまでの距離と、予め定められるセグメントの厚みの長さと、シールドマシン座標情報とに基づいて、セグメントの位置を示すセグメント座標情報を算出し、シールドマシン、掘削境界、及びセグメントの位置関係を逐次表示する。【選択図】図3
