钢板混凝土井壁极限承载能力的塑性解

根据虚功方程、平衡条件、强度准则以及流动法则写出钢板混凝土井壁满足的基本方程并求解，抗到了钢板混凝土井壁的极限承载能力的塑性解．计算结果与试验结果吻合较好，从而证明采用这种方法求解的结果是可靠的．最后根据计算结果和平衡条件，建立了该种井壁极限承载能力的计算公式，可供设计时参考．

Plastic Solution of Limiting Bearing-Load Capacity about Concrete Shaft Lining with Steel Sheet

When steel plate and concrete are assumed to be stiff-plastic material, it can respectively satisfy its strength criterion, the basic equation are set up and plastic solutions of limiting bearing-load capacity about concrete shaft lining with steel sheet are obtained by using fslse-function principle, balance condition, strength critcria and mobile rule. Compared with experiment results, the calculating results are proved to be reliable. Finally, a theorial fomula to calculate limiting bearing-load capacity of the type of shaft wall is created and used for reference in design.
