چکیده
The influence of foundation pit excavation on deformation and stability the supporting structure underlying adjacent existing tunnel is a comprehensive geotechnical engineering problem, including unloading effect coupling surrounding rock structure. Using numerical calculation methods, this paper changes different depths widths discusses evolution law about force structure, changing relationship axial anchor with distance between obtained compares way rod near tunnel. It found that increase tunnel, at top under entirely symbolizes trend increases first then decreases, leftmost from pressure to tension, decreases gradually. When depth increases, width absolutely has little

Numerical Modelling of the Segmental Lining of Underground Structures
There are several methods for analysing the behaviour of underground structures under different loading conditions. Most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. On the other hand, for stability analysis and the designing of support systems, these methods consider segme...
