Advances in the physical simulation experiment on debris flow initiation in China

  • 摘要: 为进一步提高泥石流起动物理模拟试验的科学性,完善试验体系,采用资料收集与分析方法,总结了近年来中国泥石流起动物理模拟试验开展的现状,从水流冲刷与泥石流起动试验以及人工降雨与泥石流起动试验两个方面论述了中国泥石流起动试验取得的主要进展和理论成果。在国内外泥石流起动物理模拟试验对照基础上,提出中国泥石流起动物理模拟试验研究的建议:提高水流浓度、降雨雨型与土体特征的相似率;加强降雨或水流作用下土体物理力学特征变化与泥石流起动响应研究;推动降雨与汇流共同作用下泥石流起动综合性物理模拟试验的开展。
    Abstract: As debris flows usually occur abruptly and rapidly in mountainous areas, it is difficult to observe their initiation and occurrence process. Therefore, the physical simulation experiment has been adopted as an important method to study debris flow initiation mechanism by more and more scientists. In recent years, many physical simulation experiments have been carried out and related phenomenon have played an important role both in mechanism research and in disaster mitigation. However, compared to the complex process of debris flow initiation and occurrence, there usually are some limits in the condition of physical simulation experiments. In this paper, based on data collection and analysis, advances in the physical simulation experiments including runoff type and artificial rainfall type were summarized in detail. And then by comparing the experimental study progress of both nationwide and worldwide, some factors that should be further taken into account in the physical simulation experiments on debris flow initiation were discussed. In the end of this paper, some related advices on future physical simulation experiments on debris flow initiation were put forward in the following aspects: To further improve the similarity of experimental condition, such as runoff density, rainfall type and soil characteristics, to further study the relation between debris flow initiation and the physical and dynamic variation of soil mass, and to further carry out some comprehensive experiments in which all the rainfall process, runoff process and material-supplying process are all involved.
