浅谈混凝土大坝裂缝成因及其预防措施

随着社会经济的发展,混凝土结构在工程建设中得到了广泛的应用。但大体积混凝土结构如混凝土大坝在施工及运用期间极易出现不同程度、不同形式的裂缝,对结构安全和正常运用产生了不利影响,严重影响工程寿命和经济效益的发挥。为此,本文对混凝土大坝结构中常见裂缝的成因进行具体分析．并在此基础上从结构、材料、施工及综合治理等方面提出了预防措施,从而可为混凝土结构的设计、施工和管理提供一定的理论指导。

Briefly Discussing Preventing Measures and Analyzing Reasons of Concrete Dam Crack

Along with the social economy＇s development, concrete structures are used widely in the construction. But the massive concrete structures such as concrete dam is especially likely to emerge cracks of different extent and different forms during construction and in use, which bring adverse effects to the safety and the normal use of the structures, and influence the project life and the benefit badly. Therefore, the author analyzes concretely in this paper the reasons why concrete dam cracks, and on this basis puts forward measures to avoid the cracks from different aspects such as structure design, material preparation, construction and integrated management. It may provide some theoretical guidance to the structure design, construction and management of the concrete works.
