混凝土是我国工程建设使用最为普遍的结构材料之一,其质量直接影响到结构的适用性、安全性和耐久性。为此,人们对混凝土的质量给予了极大的关注。混凝土的结构裂缝不仅种类繁多,形态各异,而且较为普遍。轻微者影响建筑物美观,造成渗漏水,严重者降低建筑结构的承载力、刚度、稳定和整体性、耐久性,甚至还会导致整体倒塌的重大质量事故。因此,正确认识裂缝成因,对混凝土结构裂缝进行调查和分析是混凝土结构检测中的重点。
Concrete is one of the most common structural materials used in engineering construction in China. Its quality directly affects the applicability, safety and durability of the structure. To this end, people have given great attention to the quality of concrete. Concrete structural cracks not only a wide range of different shapes, but more common. Slight influences on the aesthetics of the buildings, resulting in seepage of water, serious cases of lowering the bearing capacity, stiffness, stability and integrity of the building structure, durability and even major quality accidents that may cause overall collapse. Therefore, a correct understanding of the causes of cracks, cracks in concrete structures to investigate and analyze the concrete structure of the test focus.
