Elastic-Plastic Analysis of Peak Stress of Anchor in Circle Tunnel

Abstract:

In this paper,the rule of direct proportion between anchor stress and creep strain of rock mass is taken as a starting point. After tunnel excavation,stress distribution of anchor in perfect circle tunnel is analyzed,then an important conclusion that the location is coincident between peak stress of anchor and plastic zone border of rock mass can be drawn in terms of theoretical derivation when rock mass is in plasticity.
