Analysis of visualized projection stability and strengthening suggestions of China-North Kroea border highway

Basied on software AutoCAD, inserting the VAB program relizes the analysis and visualization, automatation of stability of stereographic projection attaching to fractured rock mass structure caused by building the border road ranging from K2+280 to K3+180 of the high and steep slope of Shijue in Ji´an. Through the survey of the current geographic condition the stability of high and steep slope is mainly up to joint planes, the destroy of steep edge slope is mainly due to the unstability of wedge forms after the cuting of discontinuous joint planes. Therefore, it puts forward that the analysing process of rock mass edge slope should be programmed, by which it analysed the stability of high steep edge slope of the border road ranging from K2+280 to K3+180 and comes up with the reasonale suggestion of strengthening.
