【Abstract】 Using the theory of plastic limited analysis, the authors introduce in this paper a set of equations indicating the correlation between casing deformation and load under the actions of both the opposite radial forces and the uniform external pressure and accordingly a series of load-deformation curves and discuss the variables that can affect casing deformation.更多还原
