本文针对北京市第十水厂超长混凝土墙体结构的抗裂技术进行了试验研究，试验结果表明，混凝土中掺入了膨胀剂，增强了混凝土的补偿收缩能力；同时提高混凝土配合比中的粉煤灰掺量，可以有效降低混凝土水化热，减少产生温度裂缝的风险。通过严格控制施工技术，在实际工程应用中取得了良好的效果。

The anti-cracking technology of ultra long concrete wall of the tenth waterworks is studied in this paper.The experimental results show that the shrinkage compensation ability of concrete is enhanced when concrete is mixed with the expansive agents.The hydration heat of concrete is reduced effectively when improving the mix ratio of fly ash,and the risk of temperature cracks is reduced.A good result is achieved in the engineering application through the strict control of construction technology.
