Abstract
For the initial lining structure of tunnel , constructing an consider integrated safety factor function.Consider the initial shotcrete tunnel support structure as a series system, using the interval estimation of the "wide boundaries of law" system of tunnel lining structure analysis, on this basis to determine the system failure mode. Using the limit displacement under the condition of axial force and bending moment of the corresponding displacement and construction monitoring of displacement are analyzed, considering the material properties, geometry and random effects. Using the Monte Carlo finite element method, combined with a typical project example to tunnel structural system reliability index were calculated. The calculation results show that in the engineering example, tunnel lining structure in some local section of the reliability index is smaller, but the whole support system reliability indexes meet the design requirements, the whole tunnel lining structure in a safe state.
