Dynamic Simulation and Resource Optimization of Urban Solid Waste Lifecycle Based on Digital Twin
Xiao-Ya Jiang, Si-Tong Yao, Lei Guo
The disconnect between urban solid waste management and urban planning represents a critical bottleneck for sustainable urban development. This paper proposes a digital twin-based method for dynamic simulation and resource optimization throughout the entire lifecycle of urban solid waste, establishing a collaborative platform integrating "Smart Urban Planning" and "Waste Resource Recovery" modules. Through 3D visual modeling, multi-dimensional simulation analysis (economic, engineering, and social benefits), and AI-driven dynamic matching of waste types with recycling technologies, the platform enables closed-loop management of construction and demolition waste—from generation and sorting to recycling and application. The system integrates BIM, GIS, IoT, and machine learning technologies to support real-time monitoring, dynamic early warning, and planning optimization, facilitating a shift from reactive governance to proactive optimization. Research demonstrates that the system significantly improves waste recycling rates, reduces carbon emissions and material costs in pilot areas, offering a replicable technical pathway for building "zero- waste cities."

Common Defects and Treatment Measures for Pressure Vessels
Lu-Qiu Xie
Pressure vessels play a critical role in industrial production. However, their manufacturing, installation, and operation are influenced by numerous factors such as materials, processes, and environmental conditions, making them highly susceptible to defects that pose significant safety risks. This paper provides a detailed analysis of common defects arising during the manufacturing and installation stages, including welding imperfections, geometric dimensional deviations, and surface quality issues, along with targeted mitigation measures. Additionally, it discusses approaches for addressing defects that occur during the operational phase, such as corrosion and cracking. The study emphasizes the necessity of stringent quality control to ensure the safe operation of pressure vessels.
