Study on Impact Force of Landfall and Rockfall

Article Preview

Abstract:

The original algorithm holds that the weight and impact force of rockfall are large different. For easy calculation, the rockfall own weight can be almost neglected. But the impact force of rockfall has a slow increase of the process by the resisting effect of the soil during landfall and rockfall impacting soil over the pipe, which the rockfall own weight to the contribution of the impact force is great. Therefore, it is necessary to study on impact force of landfall and rockfall. We establish the mathematical model of impact force of landfall and rockfall by mathematics and mechanics knowledge, and put forward the wallop amplification coefficient method by the count, which results more close to the actual situation, comparing with the original algorithm. It shows that result, which is better than the original algorithm results, by the wallop amplification coefficient method can be widely used in practical projects.
