住房砼的裂缝是建筑界最常见的现象,裂缝重则危及结构安全,轻则影响房屋的正常使用及砼的寿命。裂缝的形成往往是地基受力不均、构件的强度和刚度不足,或者是设计不尽合理、施工方法不当、材料选用不妥当等原因造成。本文从设计、材料、施工等三个方面提出相应的预防。 The cracks in housing are the most common phenomenon in the construction industry. Cracks jeopardize structural safety and lightly affect the normal use of the house and the life of the concrete. The formation of cracks is often caused by uneven foundation stress, insufficient strength and stiffness of the components, or due to unreasonable design, improper construction methods, improper material selection, and other reasons. This paper proposes corresponding prevention from three aspects: design, materials, and construction.
