本文讨论了土壤行为的理解和描述以及岩土工程问题的数值分析方面的最新进展。我们尝试将这些主题与涉及重大项目设计的执业工程师的需求联系起来。土性质的讨论集中在单调试验中粘土的行为模式，以及粘土的强度和刚度与有效应力水平和超固结比的重要相关性。这种行为在塑性理论的背景下进行了审查，塑性理论已成为分析土力学问题的主要框架。强调需要将土壤模型的选择和分析方法与土壤类型和工程问题的性质相匹配。强调了模型和分析简单的好处。有关会议的封面摘要，请参阅 IRRD 287689。（作者/TRRL）
Recent and current developments in the understanding and description of soil behaviour and in the numerical analysis of geotechnical problems are discussed in this paper. An attempt has been made to relate these topics to the needs of practising engineers concerned with the design of major projects. The discussion of soil properties is concentrated on the pattern of behaviour of clays in monotonic tests, and the important correlations of the strength and stiffness of clays with the level of effective stresses and overconsolidation ratio. This behaviour is reviewed within the context of plasticity theory which has become the main framework for the analysis of problems in soil mechanics. The need to match both the choice of soil model and the method of analysis to the soil type and the nature of the engineering problem is emphasised. The benefits of simplicity of both model and analysis are underlined. For the covering abstract of the conference see IRRD 287689. (Author/TRRL)
