Powder snow avalanche impact on hanging cables

In this paper we perform a nonlinear stress wave analysis to determine the forces in hanging cables under action of powder snow avalanches. Powder avalanches are serious threat communities and infrastructure mountainous regions. They endanger power transmission lines which transport electricity over avalanche prone terrain. produce an elevated air-blast that induces above ground cables, leading failure often over-turning supporting towers. We solve system three equations with appropriate boundary conditions describes internal state cable deformation directions. The impact pressures estimated by simulating motion three-dimensional model is tested numerically, obtained results good accordance experimental measurements. also investigate possibility usage as loading sensors reconstruct cloud pressures. For formulate inverse problem, it analytically time-independent case study numerically solution. • Computation Numerical verification behaviour. Usage
