导流隧洞衬砌结构计算分析研究

Study on Calculation and Analysis of Lining Structure of Diversion Tunnel

导流隧洞广泛应用于工程建设中,钢筋混凝土衬砌支护是导流隧洞的主要支护方式。目前,中国国内大部分工程导流隧洞衬砌配筋方案值得商榷。文章对导流洞衬砌结构的受力特点进行了分析研究。研究表明只要采用先进的设计理念和有效的工程措施,就能减小衬砌厚度和钢筋用量。

Diversion tunnel is widely applied in engineering construction. Reinforced concrete lining is the main support mode of diversion tunnel. Currently, schemes for reinforcement arrangement of most diversion tunnel linings need to be discussed. In this paper, characteristics of action of the lining structure of diversion tunnel are analyzed and studied. The study indicates that lining thickness and reinforcement consumption can be reduced as long as advanced design concept is applied and effective engineering measures are taken as well.
