摘要
上昆嵩水电站引水隧洞存在洞室埋深大、地应力高、高压涌突水、断层破碎带等多种不良地质条件洞段,有发生塌方、岩爆、突涌水等地质灾害的可能,对保证施工安全和工期不利。施工单位根据地质超前预报的成果,应用不良地质辅助工法和应急处理措施来防止地质灾害的发生,保证了施工安全,节省了成本和工期,为类似工程的施工积累了经验。
The diversion tunnel chamber of ThuongKonKum Hydropower Station has a bad geological conditions,such as deep buried depth,high crustal stress,high pressure water gushing,fault fracture zone.There are landslides,rock burst,water inrush geological disasters,and they are unfavorable for construction safety.According to the geological prediction results construction unit can prevent geological disasters by using bad geological section construction method and emergency measures,ensuring the safety of the construction and saving cost and time,cumulating precious experience of the similar project.
