System failure analysis based on DEMATEL–ISM and FMECASHEN Gui-xiang(申桂香), SUN Shu-guang(孙曙光), ZHANG Ying-zhi(张英芝), Wang Zhi-qiong(王志琼), Chen Bing-kun(陈炳锟), Ma Chuang(马闯) (College of materials Science and Engineering, Jilin University, Changchun 130022, China)Abstract:A new method of system failure analysis was proposed. First, considering the relationships between the failure subsystems......

Reliability analysis of retaining walls with multiple failure modesZHANG Dao-bing(张道兵)1, 2, SUN Zhi-bin(孙志彬)2, ZHU Chuan-qu(朱川曲)1(1. School of Energy and Safety Engineering, Hunan University... on the upper-bound theory of limit analysis were established, and two kinds of failure modes were regarded as a series of systems with multiple correlated failure modes. Then, statistical characteristics......
Kinematical analysis of highway tunnel collapse using nonlinear failure criterionYANG Xiao-li(杨小礼), YANG Zi-han(杨子汉), PAN Qiu-jing(潘秋景), LI Yu-lin(李育林) (School of Civil Engineering, Central South..., and test data showed that the strength envelopes of the soils followed power-law failure criterion. In this work, deep buried highway tunnel with large section was taken as objective, and the basic......
parameters and fracture morphology on the rock slopes system reliability. Key words: Barton-Bandis criterion; failure mode; probability of failure; rock slope; system reliability analysis Cite this article... deterministic analysis methods cannot effectively account for the influences of various uncertainties and multiple potential failure modes that arise from the complexity of the rock mass forming process [4......

Roof collapse of shallow tunnels with limit analysis methodYANG Xiao-li(杨小礼), LONG Ze-xiang(龙泽祥) (School of Civil Engineering, Central South University, Changsha 410075, China)Abstract:A new failure mechanism is proposed to analyze the roof collapse based on nonlinear failure criterion. Limit analysis approach and variational principle are used to obtain analytical findings concerning......
of the cavity during actual construction. Key words: shallow tunnels; three-dimensional collapse; double-layer rock mass; Hoek-Brown failure criterion; variation analysis; upper bound limit analysis...- dimensional failure analysis. For given that, YANG et al [10] derived the three-dimensional collapse mechanism of deep buried rectangular tunnels based on the Hoek-Brown failure criterion, and LUO......
