越南某电厂水池池壁混凝土结构裂缝原因分析

Reason Analysis of Water Tank Wall Concrete Cracks at a Thermal Power Plant in Vietnam

越南某电厂项目BOP区域的多个水池池壁混凝土结构发生了大面积的开裂和渗漏现象,严重影响了水池的使用功能及外观,为分析研究裂缝发生的原因并为后续工程中的裂缝控制积累经验,根据现场裂缝的实际情况及原材料检验数据,结合相关技术文献资料,对裂缝发生的原因进行了分析,认为裂缝发生的主要原因在于混凝土原材料及混凝土生产质量的控制。在后续的工程中,需要根据工程的实际情况对原材料的选取和生产过程的质量控制有针对性地提出要求,以达到理想的混凝土结构裂缝控制效果。

The concrete crack accident happened on the tanks concrete structure at BOP area of a thermal power plant in Vietnam.These cracks seriously affected the appearance and function of the concrete tanks.In order to analysis the detailed reasons and gain the related experience on crack controlling,hereby the author do the studying and analysis on the reasons of cracks based on the construction actual site situation,test result of material and the related technical documentation.According to the below analysis,the raw material and concrete producing process were the main reasons that caused these cracks.For the subsequent projects,the material and producing process shall be gained pertinent measures following the service environment to achieve the expected controlling effects.
