Generating And Propagating Of Landslide Bore

It is about the generating and propagating processes of the bore caused by the level and uniform velocity landslide. On the basis of forefathers' study, the interaction of the shock waves of torrent, and that of rarefaction to shock wave have been discussed in detail in the useof the concept of the (u, h) curve.In the situation of shock wave, the interaction caused by the situation of one shock wave catching up with another is qualitatively analyzed with the result of the wave form: reflection rarefaction and incidence shock wave.In the situation of the rarefaction chasing after the shock wave, both the analysis solve and the important relation as to the characteristics of the wave form are obtained in the use of the characteristic line method before the rarefaction catching ip with the shock wave; after thai, qualitatively, two kinds of wave forms, reflection shock wave and incidence shock wave, or reflection shock wave and incidence rarefaction, may be obtained as well as the corresponding conditions for their occurrence. In addition, quantitative research is made for the reflection wave and the incidence shock wave resulting from the interaction. The relationship of some quantitative factors like wave height and speed together with the computing method are the achievements of the research.
