大体积筏板基础混凝土施工裂缝控制技术研究

摘要

The key of mass concrete construction quality control is the crack control. During the construction, a mass concrete number of fracture and damage degree will far outweigh the structure cracks appear during the period of use. Based on the technical regulation and combined with engineering example, this paper analyzes the reason of the cracks, puts forward scien-tific and reasonable the crack control measures, finally in order to control and prevent the cracks of mass concrete.%裂缝控制是大体积混凝土施工质量的控制关键，在施工期间，大体积混凝土出现的裂缝数量及危害程度都要远远大于结构使用期间出现的裂缝。基于技术规程并结合工程实例，分析裂缝产生的原因，提出科学合理的裂缝控制措施，最终达到控制和防止大体积混凝土裂缝的产生的目的。
