摘要
夹有泡沫塑料板的双层混凝土井壁———复合井壁———是我国广泛采用的井壁形式.在任意轴对称的法向及切向荷载作用下,用Fourier积分的方法建立了井壁应力及位移的解析计算公式,分析了泡沫塑料板的力学机理,指出采用平面弹性模型进行井壁应力分析的局限性.
The composite shaft lining,two layers of concrete linings with a foamed plastic sheet in between,is widely used in China.The analytic formulae of stresses and displacements for the composite shaft lining are obtained under arbitrary axisymmetric normal and tangential loads,using Fourier integrals.The mechanism of the foamed plastic sheet is analyzed.and the limitations of the plane model for stress analysis of the shaft lining are pointed out.
