论文部分内容阅读
近年来,李国维先生在《岩土工程学报》上发表了一系列有关软土次固结论文[1-4],最新的一篇发表在2009年第一期[1]。这些论文主要采用试验手段对软土次固结特性进行了系统分析,取得了一些有益的试验成果。笔者把土体看作是软体材料,从非平衡态热力学超黏弹性理论出发,对软土次固结的特性也进行了一些研究,其中有些观点与李国维先生有所差别。为了能使岩土力学的研究园地百花齐放,进一步深入认识软土次固结变形特性,现与李国维先生就软土次固结的某些观点进行讨论,如有不当之处,敬请谅解。
In recent years, Mr. Li Guowei published a series of articles on the consolidation of soft soil [1-4] in the Journal of Geotechnical Engineering. The latest one was published in the first issue of 2009 [1]. These papers mainly used the test methods to systematically analyze the sub-consolidation properties of soft soils and obtained some useful experimental results. Based on the theory of non-equilibrium thermodynamics and hyper-viscoelasticity, the authors also consider the soil as a soft material. Some researches have also been made on the characteristics of sub-consolidation of soft soils, some of which differ from those of Li Guowei. In order to make the research field of geomechanics full bloom, further understanding of soft soil sub-consolidation deformation characteristics, and now Mr. Li Guowei soft soil secondary fixation some of the views discussed, if there is any discrepancy, please understand.
