摘要
At present underground support,especially the temporary support is involved in almost all the hydropower projects.The use of appropriate means of underground cavern support which can not only save investment,but also promote the progress of the project,has been a project goal for geological research.Bolt-shotcrete support is the most efficient mean of construction methods,but many people have suspected the effect of bolt-shotcrete support and put forward the arch support leading to the unnecessary investment and delaying the construction period.The paper discusses the example of the calculated effect of bolt-shotcrete support of Gaixia dam hydropower project 1#,and highlights the bolt-shotcrete support.
