火电厂施工中对混凝土裂缝的控制措施研究

Study on Control Measures of Concrete Cracks in Thermal Power Plant Construction

厂区地下结构及其他建筑的基础由于大体积混凝土的裂缝问题频发生,而对于电厂的工程建设和安全运行都造成了很大的影响。由凝土裂缝的成因和原理入手,对水热化现象、塑形收缩和塌落、干燥收缩、腐蚀异变等现象进行了分析;由分别从预防措施和修补措施两方面探讨了如何有效控制混凝土裂缝问题。

Due to the frequent occurrence of cracks in mass concrete due to the underground structure of the factory area and other constructions, it has a great impact on the engineering construction and safe operation of power plants. Starting from the causes and principles of cracks in concrete, the phenomena of water heating, plastic shrinkage and slumping, drying shrinkage, and corrosion change have been analyzed ; how to effectively explore the two aspects from preventive and remedial measures respectively Control concrete cracks.
