Abstract：Abstract：Research purposes：In the construction of the Taihang Mountain tunnel, the water rich and wide tension fissure zone is encountered, which the left line length is 218 m, the right line length is 200 m, single hole maximum gushing water pressure is 230 m3/h, 0.8 MPa prediction, surrounding rock is grade Ⅲ quartz sandstone. Construction has taken full face curtain grouting, work with water and peripheral grouting method.
Research conclusions：(1) The three methods can meet the requirements of excavation, construction progress are 25 m/month, 20 m/month, 39 m/month, peripheral grouting treatment of the formation has more advantages; (2) Construction with water must satisfy the advanced hole drilling single hole water is less than 40 m3/h, the total water amount is less than 300 m3/h, broken crack length is less than 3 m, otherwise, the construction safety and schedule cannot be guaranteed; (3) Compared to the full face curtain grouting, grouting hole of the surrounding grouting reduces 59%, grouting time shortens 56%, schedule 56%; (4) The whole section curtain grouting by using 2 L/（min·m） as the inspection hole water standard is appropriate, and can relax, peripheral grouting can adopt 5 L/（min·m） standard; (5) The research findings can be similar to water rich broad patulous cranny grouting water shutoff in construction application.
