本文用塑性极限分析理论,建立了对径载荷与均匀外压共同作用下套管变形与载荷间关系的方程组,并据此绘制出一系列载荷-变形曲线,还讨论了影响套管变形的诸种因素。
Based on the plastic limit analysis theory, the equations of the relationship between casing deformation and load under the combined action of radial load and uniform external pressure are established, and a series of load-deformation curves are drawn based on the analysis results. The influences of casing deformation Various factors.
