圆形有压隧洞钢筋混凝土衬砌预留人工缝的防渗漏设计方法研究

A Study of the Impervious Design Method on Reinforced Concrete Lining of Circular Water Pressure Tunnel

通过理论阐述和有限元计算分析，研究了有压圆形隧洞钢筋混凝土衬砌一种新的防渗漏设计方法，即预留人工缝的防渗漏设计法，并根据分析结果提出了设计建议。这种新的设计方法不但能够达到工程中防渗漏设计要求，同时能够节约钢筋和混凝土的用量、施工方便。

By means of finite element analysis and theoretical derivation,this paper presents a new impervious design method on the reinforced concrete lining of circular water pressure tunnel and proposed design recommendation according to the calculated results.This design method can not only meet the equirements on impervious design in engineering but also save the amounts of steel and concrete.It convenience the construction and shorten the duration for a project.
