The research shows that the time space effect of earth behind of wall is beneficial to the safety of the foundation excavation； the soil stress concentration should be avoided when the retaining structures and infrastructure are under construction; the calculation parameters of foundation excavationis conservative，so the construction sequence ensures the safety of construction.

Test results show that: ① In initial support, the anchor only piays a temporary support on rock deformation and the selfsupporting of rock and steel brace play a major supporting role. ② As the tunnel bias, the pressure is different in both sides of the same test construction reference for lining. ③ Monitoring result shows that the design parameters of Tianpingling tunnel exit of class V supporting lining structure is more safe and reasonable which can provides reference for the similar projects.
