摘要
由于巴塘水电站坝址区岩体风化卸荷和倾倒变形强烈、结构面发育且围岩破碎,导致有用料鉴别挑选及开挖困难。针对该问题,基于巴塘水电站前期勘察资料及引水发电系统现场地质编录资料建立地质三维模型,利用地质三维模型的可视化窗口,直观展示开挖边坡各结构面发育情况,进行有用料鉴别与挑选,通过控制边坡爆破顺序即可迅速开展有用料开挖工作。本次研究所取得的成果可大大加快现场施工速度、节省人力物力,具有重要的应用价值。
Due to the strong weathering unloading and dumping deformation of the rock mass in the dam site area of Batang Hydropower Station,the structural plane is developed and the surrounding rock is broken,which makes the identification and excavation of useful materials difficult.In response to this problem,based on the preliminary survey data of Batang Hydropower Station and the on-site geological catalogue data of the diversion and power generation system,a three-dimensional geological model is established,and the visualization window of the geological three-dimensional model is used to visually display the development of various structural planes of the excavation slope,and to identify and select useful materials.The material excavation can be quickly carried out by controlling the sequence of the slope blasting.The results obtained in this study can significantly speed up the on-site construction progress,save manpower and material resources,and have important application value.
