In general these new underground structures require deep excavations and it is therefore necessary to assess the influence of these excavations on existing tunnels because they may undergo displacements which may affect the serviceability of the tunnel, and additional loads on the lining may be imposed for which the lining is not designed for.</p> <div> <h4>Downloads</h4> <ul style="list-style-type:square;color:rgb(86, 170, 28);padding-bottom:5px;"> <li><a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-01-05/Iss27_5F00_Art1_5F002D005F00_Influence_5F00_of_5F00_Deep_5F00_Excavations_5F00_on_5F00_Existing_5F00_Tunnels.pdf">Iss27 Art1 - Influence of Deep Excavations on Existing Tunnels.pdf</a></li> </ul> </div><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: PLAXIS-GiD, PLAXIS 3D, PLAXIS Bulletin, PLAXIS, Tunnels, excavation</div>
