| 摘 要： | 砼的裂缝对于砼结构是一个非常重要的问题,正确判定裂缝的成因是正确处理裂缝的前提。通常的砼裂缝成因判定存在着方法复杂、时间长、代价高等问题。通过对砼裂缝产生的根本原因的分析与研究,并从裂缝的根本特性出发,将常见的砼裂缝简化为应力裂缝和变形裂缝两类,两类裂缝具不同特性。虽然裂缝产生的具体原因不同,但只要其本质特性相同,处理的方法是基本相同的,对于其产生的具体原因可不必深究。因此对裂缝成因判定的主要工作就是判定裂缝属于应力裂缝还是变形裂缝,这大大地简化了对裂缝成因的判定过程,从而以各自适合的方法进行处理。

| Abstract: | Because the concrete crack is crucial to the concrete construction, the correct judgment of the causes of the concrete crack is the premise of the correct treatment. Usually in the judgment of these causes, such problems as the complex methods, the overdue time, the high cost exist. The paper analyzes the fundamentalcause of the concrete cracks and classifies the common concrete cracks into force cracks and deformation cracks on the basis of their characteristics. By analyzing various elements of the cause of the concrete cracks, the paper points out the different features of these two kinds of cracks and puts forward new viewpoints and judgments of cracks, namely, the treatments of the concrete cracks depend on the basic features of crack. Although the specific causes of the cracks are diverse, as long as the basic features are the same, the treatments can be the same. Therefore, whether the concrete cracks belong to the force cracks or the deformation cracks is the core of the cause judgment of these cracks, which will simplify the procedure of judgment. Meanwhile the paper proposes the treatment principles. |
