| 摘 要： | 针对三峡工程永久船闸高边坡节理岩体，采用了断裂－损伤力学模型的有限元数值方法，着重分析了在压剪应力场作用下边坡节理尖端产生次生裂纹而进一步扩展的可能性及产生的附加变形，并研究了如何对这种破裂方式用锚固手段加以控制，以达到减少节理损伤演化扩展区和边坡的变形量。文中对锚固方案做了优化分析和评价。

| Abstract: | 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. |
