摘　　要：泥石流爆发后,其沉积物常淤埋城镇建构筑物与交通设施,造成交通中断与人民生命财产损失。进行泥石流爆发后的应急抢险救灾通行及泥石流沉积物未完全固结前城镇与桥梁道路的建设,需更加深入了解泥石流沉积物力学特性。通过查阅相关文献与研究成果,对近年来泥石流沉积物力学特性方面的研究内容进行比较系统的阐述与总结,指出当前研究中存在的问题与不足,并提出泥石流沉积物固结与承载计算方面需进一步研究与解决的关键科学问题。After the outbreak of debris flow,the sediment often buries urban buildings and transportation facilities,resulting in traffic interruption and loss of people's lives and property.It is necessary to understand more deeply the mechanical properties of debris flow sediments for emergency rescue and relief passage after the outbreak of debris flow and Bridges and the construction of urban and bridge roads before debris flow sediments are fully consolidated.By referring to relevant literature and research results,this paper systematically expounds and summarizes the research contents of mechanical properties of debris flow sediments in recent years,points out the existing problems and deficiencies in the current research,and puts forward the key scientific problems to be further studied and solved in the consolidation and bearing calculation of debris flow sediments.
