“…Figure 7 shows the variation of the Mohr Coulomb envelope of the direct shear test at different saturation states whose variation results are shown in Table 7, evidencing that as the degree of saturation increases, the friction angle decreases as indicated by researchers [4,6,10] showing that when the soil is saturated, it strongly affects its mechanical behavior, decreasing its strength. Inversely, when soil moisture decreases, the strength properties increase, finding a nonlinear relationship between saturation and shear strength.…”

Introduction This article is the product of the research "Variation of the mechanical properties of a soil at different moisture contents", developed in the city of Arequipa and carried out during the year 2016. Methodology: To characterize the mechanical properties of a soil according to its saturation state, carrying out 04 unidimensional consolidation tests at different saturation percentages of 0.00%, 65.71%, 80.56% and 100% and 04 direct cutting tests at different saturation percentages of 0.00%, 20%, 40% and 100%. For these tests, unaltered clay samples were extracted. Results: The results obtained from the mechanical characterization at different degrees of saturation influence the resistance to settlement and shear of the soil. Taking into account that, when comparing both resistances of the soil under study, the resistance to deformation decreased more than the resistance to shear. Conclusions: Taking into consideration that, when comparing the geotechnical parameters of the soils at each degree of saturation vary considerably, it is important to perform mechanical tests to the soil taking into account the natural moisture and not to test them in their critical or saturated state because their mechanical properties will be different, and this will directly affect the design of the foundations of the structure and therefore in the final cost of it.

The business management models are updated constantly, making it urgent to reform the teaching methods of business management courses (BMCs). Case-based teaching (CBT) is an important way to integrate the teaching and practice of business management. The construction and management of CBT resources has attracted the attention of scholars at home and abroad. This paper designed an information management system for the BMC case library. Firstly, the goals and content were summarized for the construction of the case library and the information management system. Next, the authors designed the BMC case library forms, as well as the function modules of the information management system. There are three core functions in the system: retrieval, cluster analysis, and course case allocation. At last, experimental results verified the effectiveness of the proposed case clustering algorithm and the good test performance of the established system.
