摘　　要：指出了超长混凝土楼板伸缩缝由于热胀冷缩和刚度不足,遮挡的钢板会产生变形以致损坏,易产生高处坠物伤人、渗水,存在安全隐患,针对此现象提出了"加肋起拱增加刚度法"、"加肋留槽法"、"起拱法"三种创新设计,可通过改进外观、结构和材料等改变伸缩缝的抗拉、抗压强度。经对比分析,结果表明:起拱法改进效果最为显著。Due to thermal expansion,contraction and stiffness,the expansion joints of super-length concrete plates are deformed and damaged due to thermal expansion,contraction and rigidity,which is easy to damage and cause water seepage at high heightswith potential safety hazards.To solve this phenomenon,this paper put forward three kinds of innovative design:“ribbed arch camber increased stiffness method”,“ribbed leave slot method”and“arch method”by improving the appearance,structure and material and changing the tensile and compressive strength of expansion joints.Aftercomparative analysis,the improvement of“arch method”is the most significant.
