About

SimTunnel Lite

Read full description

SimTunnel Lite is designed to perform a quick tunnel analysis on your phone device. SimTunnel Lite is very simple and easy to use. SimTunnel Lite uses "rock-support interaction" or "convergence-confinement" method to estimate the deformation of circular tunnels in weak rock, and visualizing the tunnel interaction with various support systems. SimTunnel Lite has the following features: - SimTunnel Lite determines Factor of Safety (FOS) as the ratio of maximum support pressure to the support pressure required for equilibrium. - The Tunnel and Rock Parameters dialog allows you to define the tunnel and rock properties for model. - The Strength Properties which are required will depend on the strength criteria you have selected in Setting Page. - Both Mohr-Coulomb and Hoek-Brown strength criteria are available. - The parameter calculator dialogs are available to help you to calculate some of the parameters (i.e. GSI, mi, D, UCS, insitu stress and etc). - The support parameters dialog allows you to easily add support (i.r. Rockbolt) and define the support properties for the model. - Rockbolt support type can be added to the model. - The ground reaction curve (GRC) is always displayed in the output page. - The brief summary of analysis results and input data will be displayed in the Output Page. - The report button, allows you to save the current model’s input and output information into PDF file. The generated report file can be sent out via email.
