A Study of the Impervious Design Method on Reinforced Concrete Lining of Circular Water Pressure Tunnel 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
The paper considers that the drainage works and the impervious element are the effective measures for reducing external water pressure on the lining and maintaining groundwater balance. 文章认为,设置排水设施和地层防渗加固是减小衬砌外水压力及维持地下水系平衡的有效措施。
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. 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。
