桥梁裂缝产生原因浅析

桥梁裂缝产生原因浅析(中文5000字,英文3000字)
近年来，我省交通基础建设得到迅猛发展，各地建立了大量的混凝土桥梁。在桥梁建造和使用过程中，出现了大量有关因出现裂缝而影响工程质量甚至导桥梁垮塌的报道。混凝土开裂可以说是“常发病”和“多发病”，经常困扰着桥梁工程技术人员。其实，如果采取一定的设计和施工措施，很多裂缝是可以克服和控制的。为了进一步加强对混凝土桥梁裂缝的认识，尽量避免工程中出现危害较大的裂缝，本文对混凝土桥梁裂缝的种类和产生的原因作较全面的分析、总结，以方便设计、施工找出控制裂缝的可行办法，达到预防的作用。
混凝土桥梁裂缝种类和形成原因复杂而繁多，甚至多种因素相互影响，但每一条裂缝均有其产生的一种或几种主要原因。这种混凝土桥梁裂缝，就其产生的原因，大致可划分如下几种

The bridge crack produced the reason to simply analyse
 In recent years, the traffic capital construction of our province gets swift and violent development, all parts have built a large number of concrete bridges. In the course of building and using in the bridge, relevant to influence project quality lead of common occurrence report that bridge collapse even because the crack appears The concrete can be said to " often have illness coming on " while fracturing and " frequently-occurring disease ", often perplex bridge engineers and technicians. In fact , if take certain design and construction measure, a lot of cracks can be overcome and controlled. For strengthen understanding of concrete bridge crack further, is it prevent project from endanger larger crack to try one's best, this text make an more overall analysis , summary to concrete kind and reason of production , bridge of crack as much as possible, in order to design , construct and find out the feasible method which control the crack , get the result of taking precautions against Yu WeiRan.
Concrete bridge crack kind, origin cause of formation In fact, the origin cause of formation of the concrete structure crack is complicated and various, even many kinds of factors influence each other , but every crack has its one or several kinds of main reasons produced . The kind of the concrete bridge crack, on its reason to produce, can roughly divide several kinds as follows
