高寒地区桥梁冬季混凝土施工温控技术与裂缝防控措施优化

Key Points

• The study aims to analyze the mechanisms of crack formation in concrete during winter construction in cold regions and propose optimization measures.
• Systematic analysis of crack mechanisms during winter concrete construction in cold climates
• Exploration of key technologies such as material selection, mix ratio optimization, and intelligent temperature control systems
• Proposal of optimization pathways for crack prevention measures focusing on material, construction process, monitoring, and management.
• Identified significant challenges such as reduced hydration rates and temperature stresses leading to cracks.
• Proposed effective temperature control techniques that improve early strength and durability of concrete.
• Found that optimized material selection and advanced monitoring systems significantly decrease crack incidence.
