Abstract

Abstract

Based on glide surface presumed by Terzaghi,plane strain-stress state of ground soil cell is analyzed and SMP criterion and transformed stress space are also introduced.According to the above,the ratio of semidiameter of strength envelope to average semidiameter of deviator stress in the transformed stress space with the equal mean stress is defined as the generalized strength safety factor.The relationship between foundation bearing capacity safety factor and that of generalized strength safety is also explained by geotechnical engineering practice.
- plane strain,
- SMP criterion,
- transformed stress,
- equal mean principal stress,
- safety factor
