装配式建筑以其高效、环保的优势,近年来受到了广泛关注和应用。本文以襄阳某项目工程为例,对预制混凝土(Precast Concrete, PC)结构和钢结构两种装配式方案进行了详细的比较分析。研究通过结构经济性、装配率、现场施工及后期维护等方面的综合评估,结合实际施工条件和功能需求,确定了最优方案。研究结果表明,预制混凝土结构在材料成本和施工便捷性方面具有显著优势,而钢结构在施工周期和结构性能上表现优异。最终,本文确定了预制混凝土结构为最优方案,并总结了其在项目中的应用经验,以期为未来类似工程提供参考。In recent years, prefabricated construction has gained widespread attention and application due to its efficiency and environmental benefits. This paper presents a detailed comparative analysis of two prefabricated construction schemes—Precast Concrete (PC) structures and steel structures—using a project in Xiangyang as a case study. The study conducts a comprehensive evaluation based on structural economy, assembly rate, on-site construction, and post-maintenance, taking into account actual construction conditions and functional requirements to determine the optimal solution. The results indicate that Precast Concrete structures offer significant advantages in terms of material cost and construction convenience, while steel structures excel in construction duration and structural performance. Ultimately, this paper identifies Precast Concrete structures as the optimal solution and summarizes the experiences from their application in the project, aiming to provide references for similar future projects.

牛腿开裂原因分析及加固处理方案研究——以襄阳某商务大楼项目为例

本研究通过现场数据调查、结构设计分析、施工质量问题评估及使用环境影响分析,系统研究了襄阳市某商务大楼连廊支撑牛腿开裂的成因。现场检测结果显示,牛腿开裂主要由施工质量问题引发,特别是钢筋定位不准确和混凝土保护层厚度过厚,同时锚固位置有误进一步加剧了裂缝的扩展。在分析事故原因的基础上,综合对比了多种加固方案,最终选择了外包钢加固作为主要解决方案。加固完成后,通过静载试验、超声波检测和应变监测验证了方案的有效性,结果表明加固后的牛腿在承载力和结构稳定性方面显著提升。研究最终提出了针对类似工程的建议,强调了施工质量控制和合理加固方案选择的重要性,以保障建筑的安全与耐久性。This study systematically investigated the causes of corbel cracking in the corridor support of a commercial building in Xiangyang through on-site data collection, structural design analysis, construction quality evaluation, and assessment of environmental impact. The on-site inspection results showed that the cracking was primarily caused by construction quality issues, particularly inaccurate rebar positioning, and excessive concrete cover thickness, while incorrect anchoring further exacerbated the crack propagation. Based on the cause analysis, various reinforcement options were compared, and external steel reinforcement was ultimately selected as the main solution. After the reinforcement was completed, the effectiveness of the solution was verified through static load testing, ultrasonic testing, and strain monitoring. The results indicated significant improvements in the load-bearing capacity and structural stability of the corbels. Finally, the study provides recommendations for similar projects, emphasizing the importance of construction quality control and the selection of appropriate reinforcement solutions to ensure building safety and durability.
