摘要
由于地基不均匀下沉,常使砖墙表面产生裂缝。一般性裂缝(除严重开裂外)不危及结构安全,但在地震或其他荷载作用下,容易引起提前破坏;外墙裂缝往往引起外墙渗水,影响使用。故对此应引起足够的重视,采取预防措施,减少和防止裂缝的产生,防止影响结构安全和使用。
The uneven ground subsidence often makes the brick wall surface cracks.General crack(except for severe cracking) does not endanger the safety of the structure,but in the earthquake or other loads,it can easily cause early damage.Exterior wall cracks will cause water seepage,and influent its useness.So we should pay much attention to it,adopt preventive measures,decrease and prevent the cracks of safety and then prevent affecting the structure.
