摘要
针对黄金坪水电站地下厂房围岩岩性较差的地质状况,岩壁梁开挖采取超前固结灌浆、"个性化"装药等措施,施工过程中精心设计、严格控制爆破参数,检测结果表明,爆破开挖效果良好,可供类似工程参考。
According to the poor surrounding rock properties of underground powerhouse of Huangjinping Hydropower Station, the measures such as advanced consolidation grouting and customized explosive charge are applied in the ledge beam excavation. With careful design and strict control of blasting parameters during the construction process, the test results indicate that good blasting excavation effects are achieved. The content has a certain reference value to similar projects.
