Application of Grid Rigid Frame in the Construction of Changbo Hydropower Project
The adits of headrace tunnel of Changbo Hydropower Project have some problems,such as complicat-ed geology,long length,large design scale and difficulty,and the adits are the key of headrace tunnel project,which affect the construction period of headrace tunnel.Based on the actual situation of Changbo Hydropower Project,considering the geological condition,this paper introduces the design scheme,support requirements and construction technology of reinforcement grid rigid frame for construction of adits,which can be used as refer-ence for subsequent similar projects.
