Abstract

This paper presents a case study of damage in the concrete lining of an operational tunnel by field investigation and numerical analysis, in which the field-investigated construction deficiency is considered in the numerical model, and the implemented numerical analysis is adopted for investigating the effect of damaging in the structure of the operating tunnel induced by the construction deficiency. The numerical analysis illustrates that the construction deficiency of a cavity can influence the stress state of a tunnel structure and plays an important role in the stability of the operating tunnel, which results in significant influence on the damage in the concrete lining of the operating tunnel and must be timely treated to prevent subsequent damage in the tunnel lining. Moreover, the numerical model considering construction deficiency of a cavity around the tunnel is efficient for evaluating the effect of damaging the structure of the operating tunnel induced by this construction deficiency.
