摘　　要：在深厚松散岩土层中进行隧洞开挖时预测未来开挖地段的围岩实际状况,对施工安全及提前制定相应的处理措施是非常必要的。大田水库输水泄洪(导流)隧洞运用地质预报及时掌握前方掌子面地质状况,当出现塌方冒顶时避免了人员伤亡和较大的经济损失。It is very necessary to predict the actual condition of surrounding rocks in the future excavation section when the tunnel is excavated in deep and loose rock and soil layers for construction safety and to formulate corresponding treatment measures in advance.The water conveyance and flood discharge tunnel of Datian Reservoir can grasp the geological conditions of the front palm face in time by using geological prediction,so that casualties and large economic losses can be avoided when collapse and roof fall occur.

关 键 词：深厚松散岩土层 隧洞开挖 地质超前预报 塌方冒顶 风险规避
