摘　　要：结合工程实践，探讨了某地下车库工程无梁楼盖结构体系在柱头和跨中部位发生破坏和出现裂缝的原因，并提出了加固处理设计方案。结果表明，加固处理措施效果良好，结构安全可靠，为施工和设计人员解决和预防此类工程问题提供了参考和借鉴。According to engineering practice, the author discussed the causations of damage and cracks, which occurred on position of column top and slab midspan of girderless floor system in an underground garage. Also design proposal about reinforcement cure is presented. The results show that the method of reinforcement cure is well-fitting, and structure becomes safe and reliable. The method offered references to construct and design engineer when they solve and prevent this kind of engineering problem.
