摘要
对于一般的高层建筑,在设计中普遍采用现浇剪力墙结构,并使用大流动度的泵送混凝土浇注施工,地下室混凝土剪力墙裂缝在施工中较为常见,本文以韶关某工程为例,对地下室剪力墙和楼板的强度和厚度进行了抽芯检测,并对剪力墙的开裂机理及防治措施作了具体探究,研究结果可为裂缝修复及剪力墙加固提供设计依据并为结构安全复核提供原始数据。
For the average high-rise buildings,commonly used in situ shear wall design structural design and use of high fluidity pumping concrete pouring and construction. The cracks in the basement concrete shear wall construction has become a common phenomenon in this paper as an example of a project in Shaoguan,on the strength and thickness of continuous concrete shear walls and basement floor were pumping core testing,and continuous concrete shear walls the cracking mechanism and prevention measures made specific inquiry. The results provide a basis for the design of shear walls crack repair and reinforcement and to provide raw data for the structural safety review,provide experimental evidence for the possible cause of the cracks.
