摘要
给出了有防渗要求的水工压力隧洞衬砌环向应力与纵向应力计算式,分析了隧洞衬砌产生纵向裂缝与环向裂缝的原因,提出了相应抗裂设计原则与伸缩缝间距计算式.
By the reason of circumferential crack and longitudinal crack on hydraulic pressure tunnel lining, the computation method of circumferential stress and longitudinal stress is obtained and the principales of anti-crack and computation method of expansion joint spacing are brought up.
