摘要
Abstract
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 .关键词
