Non-probability Of Reliableanalysis Of Secondary Lininings In Tunnel

The paper is based on Provincial boundary tunnel, in view of reliability problems ofthe different lining under surrouding rock of tunnel, using load—structure model. Thepurpose of this article is to calculate the lining of different cross section of the probabilityand reliability index with Interval theory. This article mainly do the research in thefollowing several aspects.1.With sorting out engineering data, the paper analyzed and solved the lining ofinternal force of shallow buried section, deep buried section and widen section with load-structure model.2.This paper introduces the basic concept,and the method and significance ofcalculate reliability index under non probability the system with the theory of intervalcomputing.3.The application of the results of all the preparation to the boundary of the tunnellining. It turns out all the lining of non probability and reliability index of each section andfind out the lining of weak and the weak lining.4.Through the control of the weak weak surface and lining, increase the probabilityand reliability index of the lining of road tunnel.5.To analyze the non probability and reliability index of whole boundary of thetunnel lining, I Put forward the method to improve the whole lining of the probability andreliability index...
