筒体结构环形板裂缝分析与处理

Analysis and Treatment of Cracks in Annular Plate of Barrel Structure

针对建筑工程中经常出现的非荷载作用裂缝的形成原因、特点规律,危害程度及治理经验,结合现行标准规范的有关要求,确保工程质量和建筑结构正常使用及耐久性。由于裂缝产生的原因较多,应该采取“抗和放”的原则,首先预防有害裂缝,设计采取预留变形缝并与施工紧密配合,采取控制措施,一般都能取得良好的效果。

To the causes, regularity, detrimental degree and treatment experience of cracks that constantly emerge due to the unload action, in combination with the relative need of the current standard ,the quality of construction and the normal use and durability of the architecture are ensured .As there are a lot of reasons that may cause cracks ,the principle of ＂prevention and setting＂ should be adopted .At first ,in order to prevent detrimental cracks ,the design of performing deformation crack, together with the construction and control measures can achieve good results.
