In this work Data Mining tools are used to develop new and innovative models for the estimation of the rock deformation modulus and the Rock Mass Rating (RMR). A database published by Chun et al. (2008) was used to develop these models. The parameters of ...

<p>Current safety requirements for both construction and operation of tunnels demand reliable monitoring and data processing methods. The conventional techniques of convergence measurements are characterized by intermittent recordings, frequently interrupting ...

<p>Using convergence tape for measuring rock movement in a tunnel during construction to control the stability of the excavation is a common practice. In this technique a number of reference points (convergence pins) are installed around the tunnel periphery. ...
