Zusammenfassung: | To provide a shield construction method support system that presents information useful for risk judgment.SOLUTION: A shield construction method support system 1 executes a process relating to a plurality of risk classifications including at least two out of excavation prohibition, ground deformation, linear deviation and lining damage monitored during a shield construction method using a shield machine 100. The shield construction method support system 1 includes: a measurement data acquisition unit 11 that acquires measurement data corresponding to excavation speed, excavation force, cutter torque, cutting face pressure, excavated soil volume, sludge discharge flow rate, pitching, rolling, back injection amount, back injection pressure, azimuth, tail clearance, and segment circularity as measurement items by using sensors M1 to M5; a subscore calculation unit 12 for obtaining a subscore indicating the influence degree of the measurement items on the risk classifications; and a total score calculation unit 13 for obtaining a total score on the basis of the subscore.SELECTED DRAWING: Figure 3
【課題】リスクの判断に有益な情報を提示するシールド工法支援システムを提供する。【解決手段】シールド工法支援システム1は、シールドマシン100を用いたシールド工法の施工中に監視される掘進不能、地盤変状、線形逸脱及び覆工損傷のうち少なくとも2個を含む複数のリスク分類に関する処理を実行する。シールド工法支援システム1は、センサM1〜M5を利用して、計測項目である掘進速度、掘進力、カッタトルク、切羽圧力、掘削土量、排泥流量、ピッチング、ローリング、裏込注入量、裏込注入圧、方位、テールクリアランス、セグメント真円度に対応する計測データを取得する計測データ取得部11と、計測項目がリスク分類に及ぼす影響度合いを示すサブスコアを得るサブスコア算出部12と、総合スコアをサブスコアに基づいて得る総合スコア算出部13と、を備える。【選択図】図3 |
