As an example, through analyses of in situ measurements of Jinyun Road Tunnel and considering the geological environment and construction technics synthetically, relation among rockmass displacement and geological tectonics, rockmass sort, horizontal displacement and vertical subsidence, a new concept"sensitivity of displacement" are presented in order to evaluate stability of displacement normally. The characteristic of distribution of rockmass displacement along the longitudinal direction of road tunnel related to geological tectonics is concluded. It can be used for reference of design, construction and research of road tunnel.
