| Abstract: | Based on a great number of measured data, zonal compressive and tensile deformation mechanism of soft rock around roadway is proposed. By using self-loading capacity of compressive zone and controlling rock deformation of tensile zone, the long bolt or short bolt group supported form is given for different size of rock compressive zone and tensile zone. The determining method of rational support parameters of bolt shotcrete and wire in different support technology is described.2figs.,1tab.,7refs. |
