摘要
本文应用极限分析的上限方法,对库仑材料立井井筒的稳定性进行研究,对于内摩擦角φ=20°的情况,通过进行非线性优化,给出了井筒极限深度的上限解答,并对不同材料参数时的机动场进行了讨论。
By using the upper—bound method of limit analysis, this paper discusses the stability of vertical shafts subject to coulomb yielding criterion. When φ=20° (φ is the inner friction angle) , this paper gives the upper—bound solution of limit depth and discusses the mechanism of varius damages for some material parameters by moans of non—linear optimization
