Construction conditions are mutual creation, in order to accurately meet the design requirements, ensure the quality of the project, ensure the construction safety, and speed up the construction progress. The overall income of mechanical and electrical engineering project is not only affected by the safe operation of mechanical and electrical engineering, but also closely related to the energy efficiency of mechanical and electrical engineering. However, at this stage, there are still problems in the construction management of mechanical and electrical engineering. If these problems can not be solved in time, it will inevitably affect the process of mechanical and electrical engineering. On this basis, starting from the installation characteristics of mechanical and electrical equipment, this paper analyzes the problems existing in the current stage of mechanical and electrical engineering construction management, and seeks measures to improve the level of mechanical and electrical engineering construction management.展开更多

The investigation centers on sheet pile design, examining two primary methodologies: Limit Equilibrium Methods (LEM) and Soil-Structure Interaction Methods (SSIM). While LEM methods, grounded in classical principles, provide valuable insights for preliminary design considerations, they may encounter limitations in addressing real-world complexities. In contrast, SSIM methods, including the SSI-SR approach, introduce precision and depth to the field. By employing numerical techniques such as Finite Element (FE) and Finite Difference (FD) analyses, these methods enable engineers to navigate the dynamics of soil-structure interaction. The exploration extends to SSI-FE, highlighting its essential role in civil engineering. By integrating Finite Element analysis with considerations for soil-structure interaction, the SSI-FE method offers a holistic understanding of how structures dynamically interact with their geotechnical environment. Throughout this exploration, the study dissects critical components governing SSIM methods, providing engineers with tools to navigate the intricate landscape of geotechnical design. The study acknowledges the significance of the Mohr-Coulomb constitutive model while recognizing its limitations, and guiding practitioners toward informed decision-making in geotechnical analyses. As the article concludes, it underscores the importance of continuous learning and innovation for the future of geotechnical engineering. With advancing technology and an evolving understanding of soil-structure interaction, the study remains committed to ensuring the safety, stability, and efficiency of geotechnical structures through cutting-edge design and analysis techniques.展开更多

Based on those theories, the conventional mining method(being called the 121 mining method) was established, consisting of excavating two tunnels with a pillar left for mining a working panel. However, with increasing mining depth,engineering geological disasters in the underground caverns have been frequently encountered. In addition, the use of the coal-pillar mining results in a large amount of coal resources unexploited. In order to address the problems above, the ‘‘Roof Cut Short-Arm Beam Theory(RCSBT), being called the 110 mining method)" was proposed by He Manchao in 2008. The 110 mining method features the mining of one coal seam panel, excavating necessarily only one roadway tunnel and leaving no pillars. Realization of the 110 mining method includes the following steps:(1) directional pre-splitting roof cutting,(2) supporting the roof by using high Constant Resistance Large Deformation bolt/cable(CRLD), and(3) blocking gangue by hydraulic props. This paper presents an overview of the principles, techniques and application of the 110 mining method. Special emphasis is placed on the numerical simulation of the geostress distribution found in the mining panel using the 110 method compared to that of the 121 method. In addition, the stress distribution on the ‘‘short beam" left by the roof cutting when performing the 110 method was also investigated using both numerical simulation and theoretical formulation.展开更多

Composition teaching is the key and difficult point in Chinese teaching. Pupils are in the initial stage of language learning, and the accumulation of vocabulary and reading is still relatively limited. They are prone to fear difficulties in writing. For primary school students, the time to learn Chinese is still relatively short, both in terms of vocabulary and reading volume, is still relatively inadequate. At the beginning of learning to write, it is easy to have difficulties in expression or words, and the frustration in learning is obvious. Therefore, in the teaching of writing, teachers must pay attention to the innovation of methods, constantly explore new teaching designs, enhance students interest in learning and reduce students writing obstacles. Next, the article starts thinking about innovating the teaching method of Chinese composition in primary schools.展开更多
