Design of Tunnel Support SystemsTYPES AND FUNCTIONS OF TUNNEL SUPPORT SYSTEMS The basic functions of a tunnel support system are to keep the tunnel stable and to make the opening usable. The specific purposes of support systems, however, depend greatly on the purposes of the tunnel. Traditionally, tunnel supports have been classified into two groups, temporary and permanent.
The properties of the beam and section are specified by typing directly into the input fields. Length of Beam is the total including all spans of the beam, in mm or ft.. Youngs Modulus is set to a default value of 200,000 MPa or 29000 ksi for structural steel, but can be edited by the user.. Area of the Cross-Section is specific to the beam section selected, and is defaulted to the values Gripper TBM - Herrenknecht AGThe rock is secured by anchors, steel mats and steel arches as well as shotcrete. Uncompromising in hard rock When tunnelling with a Gripper TBM, a rotating cutterhead equipped with disc cutters is pressed against the tunnel face with a pressure of up to 32 tonnes per disc.
