Cut and cover tunnel modelling using LUSAS

Watch how activation and deactivation of elements is used to model the staged construction process of excavating the soil, installing ground anchors and constructing the tunnel structure. A linear and a nonlinear analysis is performed to evaluate using different soil properties, and a soil stability check is carried out using the Phi-c reduction method. Live loading to simulate vehicles passing over the ground above the tunnel is applied prior to looking at bending moments in the structural elements. (Version 19.0)
