The relation between the face support pressure and the calculated tunnel face displacement gave the minimum face support pressure that should be applied on the tunnel face to avoid abrupt movement of the tunnel face. An equation is given for the minimum support pressure as a function of friction angle, cohesion, lateral earth pressure ...Cited by: 75

Strand7 plate elements support the following attributes: Local angles may be assigned to arbitrarily orientate the local x-y axis system on the plane of the plate. This allows consistent application of attributes such as face shear stress and pre-stress and for the meaningful extraction of local element stresses at nodes common to multiple elements.
