摘要
桥梁大体积混凝土的温度裂缝控制是桥梁施工中的难点,其接关系到桥梁的使用安全和寿命。论文详细阐述了桥梁大体积混凝土的结构特点与温度开裂机理、温度变化规律、温度裂缝影响因素、温度裂缝控制措施,并成功地应用到了实体工程中,为解决桥梁大体积混凝土温度裂缝问题提供了技术借鉴。
Temperature crack control of the bridge large volume concrete is difficulty in the bridge construction, which is directly related to the safety and life of the bridge. The structure and characteristics of bridge mass concrete temperature cracking mechanism, temperature variation, temperature crack factors, temperature crack control measures are described in the paper, and those are successfully applied to the real project, which can provide a technical reference for solving the temperature crack of mass concrete bridge.
