浅谈三峡右岸地下电站喷射混凝土粘结强度检测分析

Measurement analysis of the bonding strength of shotcerting of three gorges right bank underground power station

三峡右岸电站地下厂房采用了钢纤维喷射混凝土支护,通过对喷射混凝土层与层之间、喷射混凝土与围岩之间的粘结强度进行检验分析,验证喷射混凝土的强度指标和喷射工艺的标准化,保证施工质量,有效地控制了永久支护效果,对地下厂房的施工安全起到了至关重要的作用。通过对三峡右岸地下电站主厂房喷射混凝土粘结强度检验方法中存在的弊端进行的总结分析,对规范中的粘结强度指标提出了不同看法。

Steel fibre shotcreting support was adopted in the project of three gorges right bank underground power station factory building.According to measurement analysis of the bonding Strength between the layers of shotcreting and between shotcreting and adjacent rock,the strength index and standardization of ejecting technology of shotcreting was verified, This method assured the construction quality and controlled the effect of eternal support efficiently.The Shortcomings in measurement method of the bonding strength of shotcreting of three gorges right bank underground power station factory building was generalized and analyzed in the paper.Some different view on the bonding strength in code was also put forward.It can be referenced by similar project,
