%X In this paper, by using the non linear visco elastic model based on rock mechanical tests, the time dependency of ground characteristic curve of tunnel is investigated. It is found that the variation of characteristic curve with time is closely related to the time dependent behaviour of rock, especially the loading rate dependent behaviour and post failure region behaviour. And by simulation of support reaction line, the relation between ground characteristic curve and support reaction line is discussed.
