摘要
采用复变函数保角变换与曲线坐标建立了椭圆形洞室在二向不等围岩压力和均匀内压力联合作用下的应力与位移计算方法,给出了椭圆形洞室围岩应力、位移解析计算式。
In this paper ,the stress and displacement computation method under the combined action of two -dimensional unequal adjoining rock pressure and uniform internal pressure is developed from function of complex variable, s conformal transformation and curvilinear coordinate, and an analytical solution to the adjoining rock stress and displacement of elliptic tunnel is given.
