摘　　要：破碎围岩地下洞室施工中,当地质原因引起的超挖量较大,需要进行"钢拱架+锚喷"支护甚至浇筑混凝土等强支护时,采用模喷混凝土取代常规喷射混凝土或普通混凝土,不仅操作更加简便、施工更加快速,而且成本也更加节省。笔者依托柳坪电站调压室工程对模喷混凝土施工工法做了详细的试验研究,并在其他工程中进行了推广应用。Judging from the operating method,the construction speed and the project cost,the mould shotcrete method is much superior to the conventional shotcrete method or the ordinary concrete method when a large quantity of over excavation is expected and a ＂steel arched and bolt-shotcrete＂support or a poured concrete support is required.The author makes a detailed study on the construction method of mould shotcrete based on the surge chamber of Liuping Hydropower Station and recommends this method to other projects.
