混凝土温度裂缝研究采用的线性温度和应力理论与方法并不全面,此外工程现场影响混凝土温度和应力的因素众多,无法从根本上解决混凝土开裂的难题。因此,需要根据实际施工过程,对混凝土保温、通水冷却和拆模时间等进行仿真,分析裂缝成因和机理,有针对性地提出切实有效的温控防裂指标和措施,提高工程防裂安全可靠度和施工质量。在南水北调中线工程新郑市梅河倒虹吸高温季节施工中取得明显的防裂效果,值得类似工程应用推广。
The theories and methods of linear temperature and stress used in the study of temperature cracks in concrete are not comprehensive. In addition, there are many factors affecting concrete temperature and stress at the project site, which can not fundamentally solve the problem of concrete cracking. Therefore, according to the actual construction process, concrete insulation, water cooling and demolition time simulation, analysis of the cause and mechanism of cracks, targeted to put forward effective and effective temperature control cracking indicators and measures to improve the project crack safety Reliability and construction quality. In mid-South Water Transfer Project Xinzheng City Meihe inverted siphon season construction has achieved significant anti-cracking effect, it is worth promoting similar projects.
