摘要： PROBLEM TO BE SOLVED: To provide a method for accurately measuring the displacement of a ground surface or a subbase course in the case of a shield excavation by using a noncontact type distance measuring instrument.
SOLUTION: When a shield tunnel 33 is constructed, a plurality of fixed places are set at positions higher than a ground along a shield propulsion route 35, light wave type range finders 44a and 44b as the noncontact type distance measuring instruments are installed at the fixed places respectively, a plurality of measuring points 38 are set on the ground surface or near the subbase course of the upper section of the propulsion route, distances from the fixed places to the measuring points 38 are measured by the range finders 44a and 44b for arbitrary periods before the shield propulsion, during its propulsion and after its propulsion, vertical distances among the fixed places and the measuring points 38 are arithmetically operated from these measured distances, and the displacement of the ground surface or the subbase course in the shield excavation is measured from the vertical distances.
