一、对裂缝的调查及开裂原因的判断伴随着混凝土结构变形或缺陷的产生,一般总会出现裂缝。裂缝往往意味着结构的变形或缺陷。但发现的只是产生在混凝土结构表面上的裂缝,必须从表面部分裂缝来判断其危害程度。为正确判断裂缝出现的含义,需要进行调查。图1是根据混凝土工艺学协会裂缝调查委员会的工作列出的程序图。根据此程序,若发生裂缝,首先要进行标准调查,若能由此确定原因即罢,否则就要接着进行详细调查。
First, the investigation of cracks and the cause of the cracking With the deformation of concrete structures or the production of defects, cracks will always appear. Cracks often mean structural deformations or defects. However, only the cracks generated on the surface of the concrete structure are found, and the degree of damage must be judged from the cracks on the surface. In order to correctly judge the meaning of cracks, investigations need to be conducted. Figure 1 is a process diagram according to the work of the Crack Investigation Committee of the Concrete Technology Association. According to this procedure, if a crack occurs, a standard survey must be conducted first. If the cause can be determined, otherwise a detailed investigation will be carried out.
