Title: Laboratory Tests of Soil Strength and Deformability: The Triaxial Test Description: Description of different soil tests. Triaxial Test. Sánchez Romero, FJ. (2023). Laboratory tests of soil strength and deformability: The triaxial test. https://riunet.upv.es/handle/10251/19... DER Automatic description: In this video, a professor from the Department of Rural and Agri-food Engineering at the Polytechnic University explains laboratory tests for estimating soil strength and deformability, focusing on the triaxial test. The presentation is divided into five parts: introduction, soil strength parameters, description of laboratory tests, triaxial test methodology, and conclusions. The importance of understanding the capacity of soils to withstand gravitational loads is emphasized, and it is explained that, due to soil anisotropy and heterogeneity, simplifications are made for its analysis. The most significant strength parameters include deformability, bearing capacity, modulus of elasticity, Poisson's ratio, allowable stress, angle of internal friction, and cohesion. Other tests, such as the oedometer test, unconfined compression test, and direct shear test, are briefly described, differentiating their applications and what they measure. The triaxial test is highlighted for better representing soil behavior, as it takes lateral confinement into account. This test involves compressing a cylindrical specimen under hydraulic pressure until failure and allows for the estimation of values ​​such as the modulus of elasticity and Poisson's ratio, as well as the cohesion and angle of internal friction of the soil. Finally, the need to validate experimental results with recognized values ​​is emphasized, along with the implications of performing the test under different conditions (unconsolidated undrained, consolidated undrained, and consolidated drained), concluding with the relevance of these tests for determining the mechanical suitability and strength of soils.
