摘要
通过对四种裂缝,即主拉应力斜裂缝、垂直裂缝、纵向裂缝以及底板混凝土劈裂的形成原因、设计原因与施工原因的分析,提出相应的防止措施及加固措施,具有重要的工程实践意义。
By analyzing on the causes for forming, design and construction of four kind of cracks, such as oblique crack of main pulling stress, perpendicular crack, longitudinal crack and bottom board concrete split, it has important practical significance for engineering to put forward some relative measures for prevention and consolidation of cracks.
