Study on the synergy acting model of high voltage power transmission lines tower,groundwork and foundation influenced by mining
Abstract：The synergy acting mechanical model was set up by theoretical analysis method.Based on this model,the flexible curve differential equations of the iron tower trussed structure were solved according to the surface deformation curves and the boundary conditions and then the additional strain and stress in the tower trussed structure were calculated based on the equations.The study demonstrates that the movement and deformation characteristics of the tower due to undermining can be described by the synergy acting model of the tower structure,groundwork and foundation and the stress and strain of the iron tower due to undermining can be calculated by this model and it is verified through a calculated case at last.
