| In order to explore the new living space, people pay special attention to the speedy development of underground engineering recent years. So the scholars of structural engineering, rock mechanics and engineering geology get a new research direction or keystone.With the development in size and criteria of mining, hydroelectricity, trafficking, defense engineering, etc, the underground work reaches a new and unprecedented developing stage. In different kinds of rock mechanic problems to large-scale subterranean works, the continue innovation of design and calculation theory and the fast development of construction craft, both have offered essential methods to the design of rock underground engineering. Tunnel and Underground engineering are built upon experience and science, the improvement of their design level will finally depend on theory breakthrough. The national economy and defense construction is developing rapidly, at the same time, kinds of Rock and underground engineering structures are cosmically built all these will impulse the geotechnical engineering's development and technological advances.The engineering background of this paper is the 11th contract segment of Line Two of Shenyang subway. First, the deformation characteristics of tunnel surrounding rock are summarized, the deformation influence factor is analyzed, and failure characteristics of tunnel surrounding rock are concluded. Second, the deformation and stabilization characteristics of tunnel surrounding rock of 11th contract segment of Line Two of Shenyang subway is worked out with the combination of on-the-spot survey data and computer simulation. Finally, relative conclusion and suggestion is given by the study of Shenyang subway tunnel constructed with submerged excavation method. And they can be applied in engineering in the future. |
