Abstract Deep hole pre-grouting technique is applied to desist from water and reinforce country rocks in advance of tunneling. Using this technique in practical tunneling in a city，the stability of the country rocks was improved，and the tunnel had successfully passed bad geological region with fault，karst，water burst and large collapse. As a result，the safety of buildings on the ground and due data for water supply can be assured.
