With the great development of China, more and more rock road tunnels will be constructed. During the design and construction, it is necessary to know how the tunnel structure will work as time goes on. Based on the measured records during the construction of Dafengyakou and No.1 Yuanjiang tunnel in Yunnan province of China, contact pressure between the initial and secondary lining and crown displacement of the initial lining were analyzed firstly, and then the time effect on the deformation and contact pressure was carefully investigated. For example, the change of contact pressure with time can be divided into two stages and, in either stage, the change with time satisfies the hyperbolic rule. And the relationship between the crown displacement and time satisfies the exponential rule. It was found that tunnel excavation, rock creep and time-dependent modulus of concrete can affect the change of the contact pressure greatly. The conclusions obtained will be helpful for the design and construction of rock road tunnels in China.
