混凝土结构裂缝的检测与控制

Inspection and Control of Concrete Structural Crack

混凝土是一种抗拉能力很低的脆性材料,在施工和使用过程中,当发生温度、湿度变化、地基不均匀沉降等时,极容易产生裂缝。混凝土结构的裂缝开展过大将影响建筑物的美观、适用性和耐久性,严重的甚至危及建筑结构的安全。该文通过对裂缝形状、开裂规律和裂缝的检测,分析了裂缝产生的原因,阐述了裂缝的检测方法和使用范围,提出了裂缝预防与控制的方法。

The concrete is a low tensile strength of fragility material, and its crack is easy to cause in the construction and use processes because of the temperature and humidity changes, and the uneven settlement of subgrade. Too large crack of concrete structure will influence the appearance, applicability and durability of the buildings, and will endanger the safety of building structure if serious. The article analyzes the crack causes, sets forth inspection method and using range of crack and puts forward the crack prevention and control method according to the crack shape, cracking law and crack inspection.
