泥石流冲击力谱及地声谱的透视

A Perspective View on the Earth Sound and Impact Spectrum of Debris Flow

根据蒋家沟测站的几次典型冲击力与地声频谱的测验资料,与紊动水流能谱进行了模拟分析。对泥石流内部的能量传递与损耗、空间变化、时间变化作出了解释,并定性地说明了沟床的冲淤规律。相信借助于地声谱及冲击力谱进行泥石流的研究,将会取得有效的进展。

On the basis of some-typical measured data of impact load and earth sound spectrum analysis at the Jiangjia Revene Experiment Station of Debris Flow, and similarity comparison with the energy spectrum of turbulent flow, the mechanism of energy delivery and consumption among the solid particles in debris flow as well as the change of debris flow patterns in space and time are interpretated. The tendency of deformation of debris gully is also explained. It is convinced that to study the debris flow by the impact load and earth sound spectrum will be promising.
