... research that was presented by Salem et al [12]. In their suggested analytical method an explicit solution was proposed for the determination of the radial displacements and the ground pressure acting on tunnel support. It was based on a Kelvin-Voigt theological model. A closed-form solution for the...

Paper Number: ISRM-ARMS6-2010-100
... Abstract: The Longitudinal Deformation Profile (LDP) is a graphical representation of the radial displacement versus the distances to the tunnel face for an unsupported tunnel section. LDPs can be computed by numerical models. Also, Vlachopoulos and Diederichs [1] have proposed accurate...

... information, as stated above, can be a priori predicted only by numerical methods. However, the prediction of radial displacement magnitude and its path towards final convergence are also possible with closed-form solutions and different empirical relationships [1,2,3]. Since the displacements in the plane...

... general, is undertaken only behind the face allowing a certain amount of displacement, so-called ‘premeasurement- displacement’. Measured displacement is only a part of the total radial displacement. Therefore, pre-measurementdisplacement should be determined in order to characterize a complete radial...
