房屋建筑工程中混凝土结构出现微裂缝是一个很普通且不可避免的问题。其中有因温度变化、收缩、膨胀、不均匀深陷等原因引起的变形裂缝,也有因外部荷载过大而引起的荷载裂缝等。文章就这种裂缝产生的原因进行了分析,针对裂缝不同的产生原因提出了一系列的裂缝控制方法及其相关的治理措施。
The microcracking of concrete structures in building construction is a very common and unavoidable problem. Among them, there are deformation cracks caused by temperature changes, shrinkage, expansion, uneven intrusion, and load cracks due to excessive external load. The article analyzes the causes of this kind of cracks, and puts forward a series of crack control methods and related measures to deal with the different causes of the cracks.
