工民建结构产生裂缝原因及预防措施分析

Analysis on Causes and Preventing Measures of Cracks in Civil Engineering Structure

工民建结构承受着自重和外荷载的作用且受自然环境的影响,结构上的外力大于自身结构材料的抵抗力时,结构就会产生裂缝。裂缝致使结构的强度和耐久性等性能减弱,严重时可能发生垮塌。首先分析工民建混凝土结构产生裂缝的各种原因,针对不同的裂缝结合具体实例,提出不同的预防混凝土裂缝的措施,以供参考。

The civil engineering structure under dead weight and external load,which also affected by the natural environment.When the external force on the structure is greater than resistance of its own structured materials,the structure will produce crack.The structure cracks cause the strength and durability of structure to weaken and even collapse in serious case.At first lots of reasons analysis of cracks in concrete structures in civil engineering,specific examples for the combination of different cracks and put forward different measures to prevent cracks in concrete structure for reference.
