摘要: 将冻结壁视为无限长轴对称厚壁圆筒,利用摩尔-库仑强度准则对冻结壁进行弹塑性分析,得到了平面应变状态下应力场和位移场分布特征,对充分发挥冻结壁承载力和深井冻结壁设计具有一定的参考意义。Abstract: Regarding frozen wall as spatial axis symmetric thick walled cylinder,and conducting on elasto-plastic analysis on the frozen wall by Mohr-Coulomb strength criterion,the distribution rules of radial displacement field and stress field of frozen wall are got.The result is of importance in giving full play to frozen wall bearing capacity and can be taken as reference for designing the frozen wall of a deep shaft.
