Abstract

Abstract: Calculation of structural stress of inclined circular hydraulic pressure tunnel is complicated. By coordinate transformation and establishment of the corresponding mechanical analysis model, the stress on surrounding rock and lining as well as analytic solution of displacement of the spatial axisymmetric structure are obtained, which can be applied to the design of inclined circular hydraulic pressure tunnel.

Key words: inclined tunnel section, coordinate transformation, surrounding rock, lining

摘要： 水工圆形压力倾斜隧洞段结构应力计算是一个具有工程实际意义和学术价值的复杂技术问题。通过坐标变换及建立相应力学分析模型，获得了这一空间轴对称结构的围岩、衬砌应力和位移解析解，成果可应用于圆形压力倾斜隧洞段的工程设计。
