Research conclusions：To the high pressure and enriched water fault F1，the construction method of geological forecast in advance, grouting consolidation, pipe-shed support and strengthening the structure is feasible. To the main fault, the grouting purdah thickness is 8 meters besides the tunnel contour line and to the fault influence zone, if the water pressure exceeds 1. 5 MPa and the water quantity exceeds 40 m3 per hour, the grouting purdah thickness is 8 meters besides the tunnel contour line. To the other cases, it is necessary to optimize the grouting purdah thickness and construction program，reasonably equip the construction machinery and strengthen construction organization and management for enhancing the production grouting capacity to curtain grouting per cycle/32 days and the process of boring-grouting-excavation" 22 meters per month.
