摘　　要：本研究深入探讨了某地块的超长混凝土结构中地下室底板的设计特点及其功能表现。聚焦于建筑设计细节、应变监测方法、施工管理、早期抗裂效果的评估以及无伸缩缝技术的应用策略。通过采集现场数据与有限元模拟结果的比较分析,评估了纤维补偿混凝土在预防早期裂缝形成方面的效用,并提出了有效的裂缝控制措施。研究结果表明,通过精细的建筑规划和严格的施工管理,可以显著提升超长混凝土结构中地下室底板的性能和耐用性。This study meticulously examines the design and functional characteristics of the basement floors within ultra-long concrete structures,specifically situated in the block.It delves into the architectural nuances,methodologies for strain monitoring,construction oversight,the efficacy of early crack resistance,and the strategic implementation of technologies devoid of expansion joints.Leveraging both empirical data from on-site collections and comparisons with finite element simulation outcomes,this paper investigates the preventive measures against early crack formation offered by fiber-reinforced concrete.Additionally,it proposes robust strategies for crack control.Findings suggest that a combination of nuanced architectural planning and meticulous construction oversight substantially boosts the performance and longevity of basement floors in ultra-long concrete structures.
