摘要
随着河流航运的发展,船闸的数量逐渐增多,船闸的尺寸逐渐增大,混凝土裂缝问题日益突出。预防大体积混凝土产生裂缝,防止混凝土内部钢筋发生锈蚀,对保障船闸工程寿命至关重要。从船闸工程的结构特征入手,分析船闸混凝土裂缝产生的原因,从混凝土原材料、配合比、混凝土温度控制、施工工艺和构造设计等方面提出混凝土裂缝的控制措施。
With the development of river shipping, the number of locks gradually increased and the lock＇ s sizes are increased. The concrete crack becomes a prominent problem day by day. Prevention of concrete cracks and reinforcement corrosion is of vital importance to guarantee the service life of lock projects. This paper analyzes the cause of concrete crack of lock engineering, and control measures for concrete cracks are put forward from the control of raw material and mix proportion of concrete, temperature control, construction technology and constitution design.
