【Abstract】 In this paper,a computational method of the tunnels,lining and thestress of surrounding rock is established by using the temperature distributionlaw of the hydraulic pressure tunnel under the boundary condition of the exchangeheat.cnvection, considered the combined action of the temperatur.variation andinternal water pressure . Besides, a calculated formula of the spacing of expan-sion joints with the ling of hydraraulic pressure tunnel is given.The result is available for reference to designer。更多还原
