Rockfall impact static equivalent load calculation method

The invention provides a rockfall impact static equivalent load calculation method, which comprises the following steps: considering the weight of rockfall, the falling height of rockfall, the thickness of a backfill soil layer and soil layer parameters, calculating to obtain the maximum impact force of rockfall, then further calculating to obtain the maximum impact pressure of rockfall, and finally calculating to obtain the rockfall impact static equivalent load. According to the method, based on the weight of the falling rocks, the falling height of the falling rocks, the thickness of the backfill soil layer and soil layer parameters, the maximum impact pressure generated by the falling rocks on the buffer soil layer serves as a compression wave source, the static equivalent load acting on the structure by falling rock impact can be rapidly and accurately obtained according to the wave theory principle, the tedious calculation process is avoided, the effect is improved, and the method is suitable for popula
