Comprehensive Research and Analysis

Abstract

Engineering mechanics is based on the determination of material properties and microstructure, but some engineering structures will change in the process of loading, and the mode and rule of that change are unknown. For example: unfavorable structures or composite engineering structures such as flexible bending members, broken surrounding rocks, soft soil foundation, etc.; therefore, the application of engineering mechanics to solve engineering structural problems is conditional. That is to say, comprehensive research should be carried out first. When the engineering structure does not meet the above conditions, engineering measures should be taken to control the stress and the state of deformation of the engineering structure, and then an analysis of the engineering mechanics should be carried out. For example, Karl Terzaghi, the founder of soil mechanics, concluded in his later years that “soil mechanics is not so much science as technology. The most important purpose is to reasonably complete the design and construction of geotechnical engineering, and mathematics and mechanics are just the means”; for another example, Western economic theory cannot analyze the history of Western industrialization, nor the achievements of China’s reform and opening-up, and 90% of the content of economic theory is more difficult for enterprises to apply, just limited to the mathematical tools of many economists, without grounding in theory. Therefore, the comprehensive methods of research and analysis are inseparable. To solve the structural problems of highway engineering, it is necessary to carry out mathematical and mechanical analysis on the basis of comprehensive research, so as to better grasp the fundamental problem of the law of stress and deformation of the engineering structure and provide a guarantee for the correct solution of the structural problems of highway engineering.
