摘要
照壁山水库坝基灌浆试验采用孔口封闭、孔内循环、自上而下的分段灌浆法,通过试验中取得的原始资料和统计成果,对试验孔灌浆前、后单位注入量、透水率变化情况进行了对比分析。试验结果表明:灌浆试验拟定的灌浆方案适合本地区地质条件,灌浆参数经过适当修正后可直接用于生产,为同类地区水库坝基处理灌浆提供了实例。
The stage grouting method with the orifice closed and circulating in hole and from top to bottom is used for the grouting test about the dam foundation of Zhaobishan Reservoir.Through the origital test data and statistical results,the comparative analyses are made for the unit volume before and after the grouting injection and water rate changes.The experimental results show that the grouting program is suitable for the geological conditions in this region,and the grouting parameters can be directly used for production after proper revision,providing examples for the treatment of dam foundation in similar areas.
