摘　　要：研究以大渡河大岗山水电站为例,针对其坝基抗滑稳定性差的问题,收集固结灌浆相关参数,通过试验研究,将右岸A、左岸B区作为坝基固结灌浆试区,应用高压固结灌浆的方法对坝基不同类型及不同缺陷岩体予以灌浆加固,对可灌性进行分析。试验研究表明,经过加固处理,坝体整体性得到了显著的改善,同时增强了基岩强度,岩石力学参数有所改善,该施灌方法及施工工艺能够为水利水电工程坝基基础处理、固结灌浆施工提供参考。Taking Dagangshan Hydropower Station on Dadu River as an example,in view of the poor anti sliding stability of its dam foundation,the relevant parameters of consolidation grouting were collected.Through experimental research,the right bank area A and left bank area B were taken as the dam foundation consolidation grouting test areas.The high-pressure consolidation grouting method was used to reinforce different types of dam foundation and different defective rock masses,and the groutability was analyzed.The test research shows that the integrity of the dam body has been significantly improved after the reinforcement treatment,and the strength of the bedrock has been enhanced,and the rock mechanics parameters have been improved.The grouting method and construction technology can provide a reference for the dam foundation treatment and consolidation grouting construction of water conservancy and hydropower projects.
