      • General Objectives

        The general objective of the Soil Mechanics I course is to provide students with the theoretical and experimental foundations necessary to understand the physical, hydraulic, and mechanical behavior of soils as engineering materials.

        This course aims to enable students to:

        • Understand the formation, nature, and composition of soils;

        • Master the principles of soil identification and classification according to standardized systems;

        • Analyze the fundamental phase relationships (solid, liquid, air) and state parameters (water content, void ratio, degree of saturation, unit weight);

        • Study soil permeability and seepage phenomena;

        • Understand the concepts of total stress, effective stress, and pore water pressure;

        • Grasp the basic principles of consolidation and settlement;

        • Interpret the results of common laboratory tests (Atterberg limits, grain size analysis, Proctor compaction test, permeability tests, etc.).

        By the end of this course, students will be able to analyze soil behavior under different loading conditions and establish the necessary foundation for the study of foundations, retaining structures, and earthworks in advanced geotechnical engineering courses.

      • Prerequisites

        To successfully follow the Soil Mechanics I course, students are expected to have fundamental knowledge in mathematics, including basic algebra, equation solving, elementary functions, derivatives, and dimensional analysis. A solid understanding of general mechanics is also required, particularly the concepts of forces, static equilibrium, stress and strain, and the fundamental principles governing mechanical behavior. In addition, students should possess basic knowledge of physics, especially concepts related to density, unit weight, pressure, hydrostatic laws, and introductory fluid mechanics. Basic notions of general geology, including soil formation processes, rock weathering, and the identification of common soil types such as clays, silts, sands, and gravels, are also necessary to ensure a comprehensive understanding of soil behavior in engineering applications.
