PRIMARY RESEARCH ON STABILITY ANALYSIS AND REINFORCEMENT SCHEMES FOR JOINTED ROCK MASS OF HIGH SLOPE OF THREE GORGES FLIGHT LOCK
三峡船闸高边坡节理岩体稳定 分析及加固方案初步研究

The FEM with a fracture damage model has been adopted to analyse the stability of high slope of Three Gorges flight lock. In analysis, the generation of subcracks of joint tips and its additional deformation as well as the possibility of further extension are considered under the compressive shear stress condition. The effect of rock bolts for controling this type of rock failure to reduce the damage evolution zones of joints and the slope deformation is studied and optimization analysis and evaluation of different anchoring schemes are made also.
