Abstract：In order to research the forming mechanism of grouting seepage channel in the clay sand medium , Designed the grouting experiment system;And knowing the chemical grouting seepage in the clay sand medium mainly have two main forms that cylindricality seepage and surface shape seepage by the experimental result ;On the basis of Griffith criterion , deduced the minimum grouting pressure pmin that forming the Chemical grou-ting seepage channel ,Analysis the pressure loss of the Chemical grouting seepage in the medium on the basis of percolation mechanics , obtained Grouting pressure p1 that in the different positions of the seepage channel;when p1>pmin , Chemical grout will split the medium that forming new seepage channel;when p1<pmin, Chemical grout will stop split ,the Channel is closed .
