Description of the Related Art In-air displacement measurement in a tunnel is one of the methods that can quantitatively capture the movement of the ground after tunnel excavation. It is highly important to make decisions such as gender, necessity of reinforcement, and adequacy of sponsorship.

スタッフを立てることが物理的に不可能だからである。
その結果、切羽状況により初期値採取時期がバラバラと
なる。また、初期変位速度、変位量に信頼性が乏しく計
測断面間の比較が難しい。However, in such a measurement method using a convergence meter and a level staff, the initial value is extremely delayed when the ring face is bad and the ring cut method (nuclear leaving) is adopted. .. Sticking out tape in the space due to the presence of a nucleus,
This is because it is physically impossible to build staff.
As a result, the initial value collection time will be different depending on the face condition. In addition, the initial displacement velocity and the amount of displacement are unreliable and it is difficult to compare the measurement cross sections.

いことにもなる。Further, in the above-mentioned conventional method, since the tape is attached to the space and the work vehicle at a high place is used, it is necessary to interrupt the excavation / support work near the measuring point during the measuring work. Furthermore, in the above-mentioned conventional method, a plurality of hands are required for the measurement work itself, and it is not possible to measure many cross sections at once. This means that it is difficult to increase the measurement frequency and the measurement section interval, and it is easy to overlook the point where displacement occurs.

There is a risk of misunderstanding the nature and cause of displacement.
