Stress Sensitivity of Loose Sandstone and Sports Training Management Based on Image Recognition

Abstract

This paper studies the stress sensitivity and training management of loose sandstone based on image recognition in detail. Loose sandstone is one of the most common storage rocks, which accounts for a large proportion at home and abroad. In the process of developing loose sandstone reservoir, it is basic to obtain the mechanical parameters correctly. Because of the high porosity, high permeability and weak separation strength of loose sandstone, the paper discusses the influence of gap water pressure, and temperature on mechanical parameters of loose sandstone. The compressive strength of loose sandstone decreases with the increase of the gap water pressure. The elastic modulus of loose sandstone will decrease greatly under low clearance water pressure, but it is slow to decrease under high clearance water pressure, and Poisson ratio will decrease first and then increase. But the accuracy of quadratic fitting of compression strength, elastic modulus, and clearance water pressure is high, but the accuracy of Poisson ratio is low and the correlation is weak, which shows that there is no accurate correlation between Poisson ratio and clearance water pressure. With the increase of temperature, the compressive strength, and elastic modulus of loose sandstone begin to decrease, then rise, and then decrease rapidly after reaching the critical temperature. This is not good for the stability of the rock. Based on the above research, the general university physical education outside the curriculum is finally fully understood, which provides the basis for the decision-making and proposal of relevant departments. This paper uses literature, questionnaire, interview, mathematics statistics, logical analysis, and other methods to take 93 universities as the subjects of investigation. This paper investigates the status of university administration, coaches, athletes, and stadiums, and then uses SPSS12.0 system and Excel software to make statistics and processing of data, so as to provide strategies for sports training management.
