摘　　要：在固增水电站引水隧洞开挖过程中,为避免因围岩渗水、涌水、坍塌等不良地质条件造成设备及人员损失,对引水隧洞开展了地质超前预报工作。采用TGS360pro、TRT地质超前预报系统及地质雷达,成功预报了不良地质条件。项目部根据所预报的不良地质情况采取了相应的应对措施,避免了设备及人员损失,加快了引水隧洞的开挖与支护进程,确保了固增水电站引水隧洞的顺利贯通。阐述了地质超前预报在不良地质条件引水隧洞开挖中的应用过程。In order to avoid the loss of equipment and personnel caused by unfavorable geological conditions of water seepage,gushing and collapse of surrounding rock,geological advance forecast was carried out during the excavation of the headrace tunnel in Guzeng Hydropower Project,by using TGS360pro,TRT geological advance forecast system and ground penetrating radar.This paper elaborates the application procedure of geological advance forecast system in headrace tunnel with unfavorable geological conditions.According to the predicted unfavorable geological conditions,corresponding measures were taken to avoid the loss of equipment and personnel,so as to speed up the excavation and support of the headrace tunnel,and ensure the success penetration of the diversion tunnel.
