本文回顾了粘性类土起动临界条件现有的研究成果,讨论了研究中存在的难点和不足。通过和土力学中粘性土边坡滑动稳定分析类比,认为河流中粘性类土的起动分析可借鉴土力学中粘性土边坡稳定分析的研究成果。在此基础上,提出一种粘性类土的起动分析的新模式。初步的讨论表明,此模式是正确的。关于此模式的具体应用将有续文进一步讨论。 This paper reviews the existing research results of the critical conditions of viscous soil initiation and discusses the difficulties and shortcomings in the study. By analyzing the analogy with the sliding stability of clay soil in soil mechanics, it is considered that the analysis of the start-up of viscous soil in river can draw lessons from the stability analysis of clay soil in soil mechanics. On this basis, a new model of starting analysis of viscous soil is proposed. Preliminary discussions show that this model is correct. The specific application of this model will be continued for further discussion.
