摘要
针对水布垭水电站地下工程的特点及其喷射混凝土的相关试验和实际应用情况,对地下洞室喷射混凝土的以下几个关键问题进行了探讨:新奥法施工情况下的喷混凝土支护设计原则;喷射混凝土的外加剂和渗和料;增强型喷射混凝土及其必要性;喷射混凝土韧度的测试方法。通过这些问题的探讨,得出了一些基本结论,对相关工程有参考价值。
This article discusses the several key problems to the shotcrete of the underground cavern aiming at the Shuibuya Hydropower Stations, the characteristics of the underground project, and the relational test as well as its application These problems are the support design principles of shotcrete by applying the NewAustria Method construction, the shotcrete's admixture, the strengthtype shotcrete and its necessity, and the test method of the shotcrete's toughness Some basic conclusions have been gained and can be used for reference in the similar projects
