| 摘 要： | 文章目的在于揭示超深立井岩石开挖后，井帮围岩在地应力重新分布情况下的应力变化情况，然后利用围岩的强度准则和变形标准来分析围岩的稳定性，进而为是否采用临时支护提供理论依据。文章的理论分析过程，应用了弹性力学中轴对称理论、应力集中原理和库仑-纳维尔强度准则。本文的研究成果，可作为基岩段井壁结构设计的依据和快速掘进方案制定的基础。

| Abstract: | The purpose of this paper is to find the information of the stress change of surrounding rock when ground stress is redistributed after rock is duged in deep shaft. On the basis of above result, the stability of surroundung rock are analysized by the strength rule and deformation standard, then theories foundation is provided for whether temporary support is needed. In this paper, the axial symmetry of mechanics of elastic bodies, the principle of stress concentration and Ku Lun-Naiwel strength rule is used. The research result may be as the basis of the design of shaft costruction in rock range and the basis of the establishment of speediness driving. |
