Abstract

The factors that determine the geotechnical behavior of soils are mainly their composition, the size of their grains and their moisture content. The design of a soil structure or foundation project must ensure the shear adequacy of the soil in all phases of construction and throughout the life of the project. However, the shear strength, in general, of the soil is not "constant" but depends on key external factors such as the prehistory of loads, the time and succession of load states, the overpressure of the pore water as well as other factors such as relative density, or any preload, the pressure field, the rate of change of the intensive state, etc. The influence of the deformations as well as the change of the intensive state during the sampling should not be ignored. Unlike other materials, in clay materials the determination of shear strength and its interpretation is a very complex problem. The aim of this article is to search for the mechanical behavior of clay soils (lignite, kaolinite, marl) as shown by the laboratory illustration related with the problems on shear strength of materials, based on the results of experimental research

粘性土力学性能评价原则

决定土壤岩土性能的因素主要是它们的组成、颗粒的大小和水分含量。土结构或基础工程的设计必须确保在施工的各个阶段和工程的整个生命周期中土的剪切充足性。然而，一般情况下，土的抗剪强度不是“恒定的”，而是取决于关键的外部因素，如荷载的史前状态、荷载状态的时间和顺序、孔隙水的超压以及其他因素，如相对密度，或任何预载荷、压力场、强度状态的变化率等。在取样过程中，变形的影响以及强度状态的变化是不可忽视的。与其他材料不同，粘土材料抗剪强度的测定及其解释是一个非常复杂的问题。本文的目的是在实验研究的基础上，通过实验室的图示，探讨黏土(褐煤、高岭石、泥灰岩)的力学行为与材料抗剪强度的相关问题

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
