为研究椭圆形断面巷道围岩弹性应力分布特征,采用复变函数解法对椭圆巷道围岩弹性应力进行了解析,得出了应力分量的曲线坐标表达式,并对不同铅垂轴长与水平轴长比在不同测压系数下围岩应力分布规律进行了分析,以期为实际工程应用提供依据。
In order to research the elastic stress distribution characteristics of elliptical section roadway surrounding rock, this paper analyzed the elliptical roadway surrounding rock elastic using complex variables function method, obtained the curve coordinate expression of earnings compo- nents, and analyzed the surrounding rock stress distribution rules of different vertical axis length and horizontal axis length ratio under different pressure coefficients, in order to provide basis for practical engineering application.
