土力学是建设海洋工程构筑物,如围填海、海上堤坝工程、人工岛、海上和海底物资储藏设施、跨海桥梁、海底隧道工程
以及海底管道等工程的重要基础。通过本课程的学习,学生将初步了解土力学特征以及计算方法及相关规范,懂得土力学
这门土木工程基础学科在海洋工程中的重要作用。首先,通过对土的物理性质及工程分类的学习,了解土的成因与组成以
及物理性质指标,掌握无粘性土与粘性土的物理性质的区别,掌握土的结构性、压实性以及工程分类等。然后,通过土的
渗透性和渗流的学习懂得土体作为由颗粒构成的多孔介质,土颗粒与孔隙水之间的相互作用,导致土体具有渗流特性以及
有效应力原理等。进而进一步学习掌握地基中的应力计算方法。通过土体的压缩性、固结理论以及地基沉降计算,掌握土
体的变形规律和计算方法。通过土的抗剪强度、地基承载力以及边坡稳定分析掌握土体强度计算方法以及稳定性分析的方
法。通过土力学的学习,学生掌握土体力学分析计算的基本方法,为进一步学习海洋工程结构物的基础的设计奠定基础。
Soil mechanics is essential for the design and construction of marine engineering structures, such as reclamation,
offshore dams, artificial islands, offshore and submarine material storage facilities, cross-sea bridges, subsea tunnel
projects, submarine pipelines etc. By learning this course, students will understand the characteristics of soil mechanics,
its calculation methods and related specifications, and understand the important role of soil mechanics in ocean
engineering. First, by studying the physical properties and engineering classification of soil, students will understand the
formation and composition of the soil, the physical property index, the difference between the physical properties of non-
cohesive soil and cohesive soil, as well as the structure, compaction and engineering classification of soil. By studying
soil permeability and seepage, students will understand that because soil as a particle aggregation porous medium, the
interaction between soil particles and pore water are very important in the analysis of soil mechanics, and will
understand the soil seepage characteristics and effective stress principle, as well as the calculation method of stress in
foundations. By studying the compressibility of soil, consolidation theory and calculation of foundation settlement,
students will understand the deformation law and calculation method of soil. By studying the soil shear strength,
foundation bearing capacity and slope stability analysis, students will understand the calculation method of soil strength
and stability analysis method. In all, by attending this course, students will grasp the basic methods of soil mechanics
analysis and calculation, which will be the fundamental knowledge for further studying of the design of the foundation of
ocean engineering structures.
