Discussion on the Calculation and Analytic Method of the Surrounding Rock of Tunnel on the ADINA

Hong Wang, Lei Liu, Liu Xiang

Abstract

Space of surrounding rock pressure is caused by underground excavation surrounding rock mass and the supporting force of deformation or destruction. Weight model, reduction weight model, tunnel specification and finite element model are four commonly surrounding rock pressure calculation methods. This paper put forward a more reasonable tunnel surrounding rock pressure calculation model by using the finite element analysis software, numerical simulation of tunnel excavation and comparison and analysis of the four calculations results.
