Title: Comparison of Numerical and Analytical Methods of Analysis of Tunnels
Author: Elarabi, Hussein; M. Mustafa, Ahmed
Abstract: This paper aims to enumerate the methods used in tunnels analysis and construction procedures, demonstrate and evaluate the use of PLAXIS 3D tunnel program through a comparison with analytical method. Two methods (analytical and numerical) have been used to obtain the solution of tunnel analysis. A case study was performed for London Transport Fleet Line, located in Green Park and consists of a single tunnel. The analytical solution carried out using the Bobet method, whereas the numerical accomplished by finite element PLAXIS program. Two different process of numerical analysis were conducted; with and without respect to construction process. The settlements at the tunnel center for the analytical, numerical without respect to construction and observed were found 7.9, 5.72 and 6.1 mm.
