本文推导出在非均布荷载作用下复合井壁的内力表达式,认为应考虑圆形井壁的曲率,给出井壁应力计算公式.并且通过一算例,把导出的井壁应力公式计算结果与国内、外广泛采用的H·林克按在梁的应力公式计算结果加以比较,得出了H·林克公式应力误差较大的结论.因此,作者建议对非均布水平荷载作用下复合井壁的内应力计算,采用把圆形井壁视为曲梁的应力计算公式.
In this paper, the internal force expression of compound shaft lining under non-uniform load is deduced, and the curvature of circular shaft lining should be considered, and the calculation formula of shaft wall stress is given. And through a calculation example, Compared with H • Link, which is widely used both at home and abroad, according to the calculation formula of the stress in the beam, the conclusion is drawn that the stress error of H. Link formula is larger, therefore, The calculation of the internal stress of the shaft wall adopts the formula of calculating the stress of the circular shaft wall as the curved beam.
