采用物化综合检测技术，对隔河岩工程帷幕灌浆部位所取芯样进行了化学分析和矿物成分、微观结构及微区元素等项试验研究。结果表明：经高压灌入岩石裂隙、断层和粘土中的水泥浆体水化较完全，结石与岩石、粘土胶结良好，灌浆处理后所取试样物理化学性能得到改善，防渗帷幕质量达到设计和施工要求。 The physical and chemical comprehensive testing technology was used to study the chemical analysis, mineral composition, microstructure and micro-element elements of the core samples taken from the grouting site of Geheyan Project. The results show that the cement slurry in the fault and clay is completely hydrated by high pressure infiltration into the rock fissures, the stones are well cemented with rock and clay, the physical and chemical properties of the samples taken after the grouting treatment are improved, and the anti-seepage curtain quality reaches the design And construction requirements.
