| Abstract: | After consultation with the experts most of the reinforced concrete lining has been eliminated in the design of the underground powerhouse crown support for the Dachaoshan Hydropower Project. This paper makes a study on the underground powerhouse crown support that is affected by the soft and weak seams from the engineering treatment point of view, and also discusses the concepts of "internal support" and "External support" derived herefrom as well as their application in the construction of this project. |
