Title: Creep analysis of soft surrounding rocks of the tunnels with the power exponential model
Abstract: The deep tunnel in the Guhanshan coal mine near Jiaozuo City is excavated in the soft surrounding rocks,which is the soft mudstone.As the rock is easy to expand when it becomes wet and the deformation may continue for a long time,the support and maintenance for tunnels become very difficult, and the production is affected seriously.Based on the field geological data and the related parameters of the rocks in the mine,the deformation of the surrounding rocks of the tunnels is simulated by using the power exponential model of the FLAC program.The results of numeral simulation agree well with the actual measurements.
