大体积混凝土基础有害裂逢的防范

Discussion on the Prevention of Harmful Crack Generation in Mass Concrete

大体积混凝土在施工过程中由于设计、施工质量不当,其内部容易出现深度不同的裂纹及通逢。对重要的设备基础一旦出现有害裂纹或通逢,基础将重新施工。从大体积混凝土有害裂缝产生的原因,分析了大体积混凝土基础产生有害裂纹及通逢的预防。

For the reason of design problems or poor construction during the construction process,mass concretes are likely to have various depths of cracks and defect seams inside.For the significant basis for key equipments（dynamic load）,once the cracks or seams exist,the basis have to be exploded and then reconstructed under certain severe conditions.In this paper,how to prevent harmful cracks and defect seams during the mass concrete construction was introduced.
