<b>Support Estimation Using Ground Reaction Curves</b><br><br> <i>RocSupport</i> is an interactive software tools for estimating ground support for circular tunnels in weak rock. By varying input such as tunnel radius, rock properties and support parameters, users can visualize the interaction between the rock mass and various support systems. <i>RocSupport</i> also calculates factor of safety or probability of failure for support. For advanced tunnel design use our finite element program <i>RS2</i>. <br><br>For a comprehensive program overview, including a description of available features and options, see the <a href="http://rocscience.com/help/rocsupport/webhelp4/RocSupport.htm">Online Help</a>.
