混凝土施工中裂缝的防治措施及处理办法

混凝土的推广使用已有一个世纪,目前在现代工程建设中仍占有重要的地位。而在今天,混凝土的裂缝较为普遍,在桥梁工程中裂缝几乎无所不在,尽管我们在施工中采取各种各样的措施,但收效甚微,裂缝仍然时有出现。该文指出,究其原因,人们对混凝土温度变化所产生的应力注意不够是其中之一,尤其是大体积混凝土。对此,温度应力与温度控制具有重要的意义。

Preventive Measures and Treatment Method of Cracks in Concrete Construction

The concrete has been spread and used for a century,and still occupies the important position in the modern engineering construction now.But now,the concrete cracks are more common,and are almost immanent in the bridge engineering.Various measures are taken in the construction,but produce very little effect and the cracks still appear sometimes.The article points out that one of its reasons is the people do not pay enough attention to the stress produced by the concrete temperature variety,especially the bu...
