The chief objective of the article is to learn the spatial characteristics of stress distribution around a shallow buried cylinder Karst cave in limestone strata. Firstly, taking into account the geometry of limestone formations, and the characteristics of Karst geomorphology in China, a spatial axial-symmetrical hollow model was established. Concurrently, combining available work and the concept of elasticity, the boundary conditions are determined. Subsequently, Love displacement method was introduced, the expressions of stress components were gained. The diagram characteristics of each stress component are summarized, which are affected by various influencing factors. Finally, in order to prove the rationality of the general solution, numerical simulation was carried out on the basis of practical engineering, and the maximum error is less than 5%. Thus, the analytical solution could represent the spatial characteristics of stress distribution around a shallow buried cylinder Karst cave in limestone strata.

With the development of civil aviation industry, the number of retired aircraft is increasing year by year. How to deal with retired aircraft, build aviation, avoid damage to the ecological environment, and develop their residual value has attracted widespread attention internationally, and gradually formed dismantling industry for the commercial and reuse of retired aircraft. From the perspective of the industrial chain, the essence of aircraft dismantling is how to maximize the value of high-value assets at the of their life cycle, that is, to balance the value of aircraft parts and the value of the whole aircraft, which is the last chain in the complete industrial of civil aircraft from design, manufacturing to usage and retirement. The paper studied the dismantling industrial modes of civil aircraft, analyzed the problems and challenges faced by aircraft dismantling, and put forward relevant measures and suggestions, which point out the direction for the development of domestic civil aircraft dismantling industry.

This paper focuses on the roles of smart manufacturing and digital economy integration in driving the transformation and upgrading of the manufacturing industry. Smart manufacturing integrates advanced technologies such as automation and digital twin, while digital economy takes data as the core driver. Many studies have shown that automation and digital twin technologies can effectively improve productivity, reduce costs and enhance production flexibility. The smart shop floor control system based on digital twin and IoT involves several key technologies such as digital twin integration interface, shop floor modeling and simulation analysis. The deep integration of these technologies not only improves production efficiency and product quality, but also optimizes resource allocation, reduces energy consumption, and provides strong support for the sustainable development of high-end manufacturing. This study provides theoretical basis and practical guidance for the intelligent transformation of manufacturing industry.

With the growing emphasis on digital technologies and cultural heritage in vocational education, the effective integration of modern technologies with traditional culture has become a central focus of current pedagogical reforms. This study explores strategies for incorporating Web3D technology and chuanzheng culture into the “reverse engineering technology” curriculum. By leveraging Web3D technology for the digital restoration and visualization of chuanzheng culture, students can engage deeply with its historical and technical significance in a virtual environment. Furthermore, integrating chuanzheng culture into the “reverse engineering technology” course enhances the content and instructional methods, fostering students′ practical skills and cultural awareness. This innovative approach enriches the curriculum, increases student engagement, and strengthens cultural identity, offering a novel teaching model for vocational education.
