Limit Analysis of Supporting Pressure for Failure Surface of Deep-Buried Tunnel with Nonlinear Failure Criterion Kan Huang 1,2 and Baochen Liu1, Jianguo Peng2 and Fu Huang 1 1School of Civil Engineering and Architecture, Center South University, Changsha, Hunan Province,China 2Transportation Planning Survey and Design Institute in Hunan Province Changsha, Hunan Province,China hk_616@sina.com , hk_616@sina.com Keywords: deep-buried tunnel, limit analysis, non-linear failure criterion, failure surface, velocity discontinuity curve.
At present, in the field of tunnel engineering, the limit theory is focused on the stability analysis of shallow tunnel excavation surface [5-10], while for the deep-buried tunnel, due to the high stress environment, after excavation, deformation, loosening and collapse of the top rock mass would be limited in a scope.
From the view of engineering practice, smallerm,smaller and larger are good for the stability of surrounding rock on the top of deep-buried tunnel.

Numerical Investigation on the Failure Behavior of Brittle Granular Chain under Impact DONGXIN LIUa, LUMING SHENb *, ITAI EINAVc and FRANCOIS GUILLARDd School of Civil Engineering, The University of Sydney, NSW, 2006, Australia adongxin.liu@sydney.edu.au, bluming.shen@sydney.edu.au, citai.einav@sydney.edu.au, dfrancois.guillard@sydney.edu.au Keywords: Brittle Granular Chain, Impact, MPM, Elasto-damage Model, Failure Behavior Abstract.
Introduction The dynamic response of granular media under impact such as stress wave propagation which was studied in detail by Kolsky [1] has drawn more attention [2,3] recently because of its extensive potential applications in geological science, earthquake science, mining engineering, soil mechanics, petroleum production, pharmaceutics etc. [4-6].
Studying such problems may provide new insight into the propagation of fragmentation waves in granular systems, and accurately predict responses of granular materials under impact and blast loading, which could eventually contribute to the failure controls in block cave mining processes and petroleum industry as well as in the earthquake engineering.
