Stress characteristics of prestressed anchor cables under explosive waves

It is significant to study the stress characteristics of different types of prestressed anchor cables under explosive waves for improving the anti-explosive performance of anchorage chamber.The model tests and numerical simulation are adopted to study the variation of stress characteristics at the end of anchor cables and the axial strain of anchorage segments under explosive waves induced by the centralized charge.The variation laws of two types of anchor cables are introduced,and some valuable conclusions are drawn.The results computed by the explicit dynamic analysis software are similar to the experimental data,and the effectiveness and correctness of parameter selection and model establishment are proved.
