摘要
东湖输水工程8号、9号洞控制段围岩岩性以凝灰岩为主,岩石节理裂隙较发育,地质情况复杂。围岩加固的效果对引水隧洞衬砌质量及工程使用寿命影响较大。为确保工程质量,在全面实施固结灌浆前,先选取代表区域进行固结灌浆试验,试验结果表明固结灌浆试验方法和参数满足设计要求,可用于施工。
Tuff is mainly available for surrounding rock at the control section of No. 8 and No. 9 tunnels of East Lake water transfer engineering. Rock joint fissures are developed and geological conditions are complex. The effect of surrounding rock reinforcement has great influence on diversion tunnel lining quality and project service life. In order to ensure project quality, consolidation grouting test was carried out on the selected representative area before the full implementation of the consolidation grouting. The test results show that the consolidation grouting test method and parameters can meet the design requirements and can be used for construction.
