摘要
大朝山水电站地下厂房顶拱支护设计方案经有关专家咨询后取消了大部分钢筋混凝土衬砌，本文从工程处理角度对主要受软弱夹层影响的地下厂房顶拱支护问题进行探讨。从而引出“内支护”和“外支护”的概念，以及探讨二者在本工程中的应用。
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.
