Assuming that a spindle shape body is made from around rods with rods destruction, and based on upper limit of plastic limit equilibrium in soil body, the problem about stability of deep excavation slopes by anchor and determine of anchor length and anchor spacing is studied.
根据土层锚杆的破坏形式通常以水泥砂浆周围土层发生剪切破坏为主,在假设锚杆破坏时在土体中形成纺锤型破坏体的基础上,基于土体塑性极限平衡理论的上限分析法,对土层锚杆支护的深基坑边坡稳定性,锚杆长度及间距的确定方法等问题进行了探讨,其结论对今后深基坑锚杆支护工程设计具有一定的参考价值。
Attentions are paid to the problems,such as different anchor length,anchor space,shoring obliquity and surface thickness.
