在桥梁建造和使用过程中,出现裂缝是一个困扰工程技术人员和工程维护人员一个常见问题,工程的破坏、寿命减少和倒塌大多是由裂缝扩展开始。如何在施工中减少裂缝的出现和运营中对裂缝的宽度控制是一个关键。本文笔者结合施工过的实际经验,对桥梁工程中裂缝的出现、原因、分析、防治等有如下见解。 Cracks in the construction and use of bridges are a common problem plaguing engineers and maintenance workers. The destruction of works, the reduction of life expectancy and the collapse mostly start with the expansion of cracks. How to reduce the occurrence of cracks in the construction and operation of the crack width control is a key. In this paper, the author combined with the practical experience of the construction, the bridge engineering cracks, causes, analysis, prevention and treatment have the following insights.
