【摘要】 地下车站结构顶板在施工过程中出现裂缝,从理论上分析推导出裂缝产生的原因,并据此提出裂缝处理方案。裂缝经堵漏与补强处理后,结构的防水性能与耐久性满足设计要求。为有关混凝土裂缝处理的工程问题提供一种思路与参考。更多还原

【Abstract】 Cracks occurred in the ceiling of metro underground station during its construction. The reason why cracks have developed is analyzed theoretically, and based on it the treatment solution is proposed. After repairing, the structure meets the requirement of waterproof and durability fixed in the design. It can be taken as reference for projects related to concrete crack treatment.更多还原
