| Abstract: | Based on the bearing capacity of a section of reinforced concrete structural member,the failure patterns related to the structural member and structural system of renforced concrete (RC) tunnel lining in weak rock are discussed,and the corresponding limit-state equations are proposed respectively.After that,a calculation method of the structural system reliability,named Point Estimate Method,is established and its formulas are given out based on the conditional probability and numerical analysis. The calculation procedure of the structural system failure probability is also put forward.In the end, the proposed method is validated by the relevant examples of tunnel lining design calculation. |
