摘　　要：地下室超长结构在温差、混凝土收缩等作用下,极易出现裂缝,不但影响工程质量,还影响使用功能。通过对地下室外墙板采用无粘结预应力抗裂施工工艺,克服了温差、收缩等引起的拉应力,达到了控制裂缝的目的。Under the influence of temperature difference and concrete shrinkage, the uhra-long structure of basement can easily crack, which not only affects the engineering quality, but also affects the function. The tensile stress caused by temperature difference and shrinkage is overcome by using non-bonding prestressed anti-crack construction technology for underground and outdoor wallboard, which achieves the purpose of controlling crack.
