Other AbstractA reasonable calculation method of rockfall impact force is very important to the design of hangar tunnel. To find a reasonable and correct rockfall impact force calculation method, several kinds of existing impact force calculation methods for rockfall were studied,and the theoretical basis and the faultiness of these methods were compared.Aiming at the problems in the existing calculation methods,an impact duration calculation formula was introduced in the Tunnel method, so it can reflect the effect of rock quality, thickness of the buffer layer and striking velocity. An amplification factor was also used, forming an improved calculation method. By comparing the improved method and other existing methods, the credibility of this new method was proved. And the results of numerical simulation also proved this. The results confirmed that the improved impact force calculation method was more accurate
than the Subgrade method,Tunnel method and Yang Qixin method. At the same time, the new method made up the defect of the theory foundation and oblique impact problem in Japanese and Swiss methods. The improved calculation method provided a new theoretical basis for the design of hangar tunnel.
