摘要
超长混凝土结构由于材料、形状的特点和外界环境的影响,会产生温度收缩裂缝,降低结构的耐久性和整体性。超长混凝土结构的设计和施工中可以采取设置后浇带、采用微膨胀——补偿收缩混凝土或设计无粘结预应力混凝士结构来防止温度收缩裂缝的产生。
The characteristics of the shape and material of Super - length Concrete Structure and the effect of the using environment always produces crack on the structure. The designer can set post - pouring belt, using UEA concrete and designing pre -stressing concrete structure to avoid the crack caused by temperature and shrinkage.
