混凝土裂缝的分析与控制摘 要近代科学讨论和大量的混凝土工程实践证明，在混凝土工程中裂缝问题是不可避开的，在一定的范围内也是可以接受的，只是要实行有效的措施将其危害程度控制在一定的范围之内。实际上混凝土结构裂缝的成因复杂而繁多，甚至多种因素互相影响，但每一条裂缝均有其产生的一种或几种原因， 所以我们要运用现有科学和知识在混凝土生产以及施工过程中有针对性地实行预防措施，尽可能实行有效的技术措施控制裂缝，使结构尽量不出现裂缝，或尽量减少裂缝的数量和宽度，特别是避开有害裂缝的出现，把裂缝控制在建筑物可以接受的范围内。以确保工程质量，使建筑物具备良好的耐久性和结构稳定性。关键词：混凝土裂缝 成因 预防措施 控制裂缝 耐久性 稳定性Concrete crack analysis and controlAbstract The modern times scientific research and the massive concrete projectpractice proof, in the concrete project the crack question isinevitable, also is may accept in the certain scope, only is must takethe effective measure its harm degree control in the certain scope. Infact the concrete structural cracks origin complex and is many, evenmany kinds of factors mutual influence, but each crack has it to haveone kind of or several kind of reasons, therefore we must utilize theexisting science and the knowledge have pointed in the concreteproduction as well as the construction process take the preventivemeasure, adopts the effective technical measure control crack as faras possible, causes the structure as far as possible the present crack, or reduces the crack as far as possible thequantity and the width, specially avoids the harmful crack theappearance, the crack control in the scope which the building mayaccept.Guarantees the project quality, causes the building to havethe good durability and the structural stability.Key word: Concrete crack Origin Preventive measure Control crack Durability Stability目 录摘要………………………………………...
