| Abstract: | The Unit Force Method is established for non-coordinate analysts of continuous andnon-continuous body in this paper.In dealing with the unknown contacting force between ice sheetand cone, an imaginary movable loading system composed of a rigid component is proposed.Theice load on cone is studied. and orthogonal numerical calculation for some parameters is performed.The formulas of ice load on cone are obtained using nonlinear regression for multiple variables.The effect of every component of ice load acting on cone on the safety of pillar is analyzed. |
