摘要： PURPOSE: A measuring target for measuring displacement and subsidence is provided to allow the measuring target attached to a tunnel to be not buried. CONSTITUTION: A measuring target for measuring displacement and subsidence comprises a target part(26), a base member(24), and an elastic spring(18). The target part is reflected for measuring of displacement and subsidence of a tunnel. The base member is inserted inside of the tunnel in order to attach the target part to the inner surface of the tunnel. The elastic spring has a specific length in consideration of the thickness of shotcrete of the tunnel. The elastic spring is fixed between the target part and the base member. A first screw insertion part(30) is integrally formed on one side of the elastic spring.
