摘要
分析了隧洞的温度分布,建立了温度应力和内水压力耦合作用下隧洞衬砌伸缩缝的间距及裂缝宽度的计算公式,并将其计算方法运用于新疆玛纳斯河老虎嘴水电站隧洞,使隧洞衬砌伸缩缝设计更加合理、经济。
The temperature distribution of tunnel is analyzed. The calculation formulas for the expansion joint spacing and the crack width in the tunnel lining in the coupling action of the temperature stress and the internal hydraulic pressure are formulated. Furthermore, the calculation methods are applied in the tunnel of Lahuzui Hydropower Project on the Malasi River, Xinjiang so that the design of the ex- pansion joint in the tunnel lining is more reasonable and economical.
