Empirical assessment of overbreak during shallow tunnel construction

Abstract

Assessment of ΤΒΜ tunneling conditions and potential for damage is of greatest benefit in resolving problems associated with the construction of shallow urban tunnels. In this predictive philosophy an overbreak risk assessment method was developed based on intuitive simplicity, theoretical background and past experience. The method evaluates ground conditions from boreholes and defines risk on the basis of hazard severity and likehood of occurrence. As the method proved macroscopically efficient, research on the subject is ongoing with evaluation of monitoring data gathered during construction.
