摘要
裂缝是道路桥梁工程中常见的病害之一,裂缝的产生与发展会造成结构的整体性及耐久性下降。裂缝不但数量大,而且产生的原因众多,按照道路桥梁工程建设过程,能够划分为设计原因与施工原因两部分,不同原因产生的裂缝需要采用不同的处置方法。文章基于对道路桥梁裂缝危害的分析,分析温差裂缝、沉降裂缝、荷载裂缝等道路桥梁裂缝的常见类型及其成因,然后以广东省某新建高速公路为例,通过裂缝病害调查研究,结合道路桥梁存在的裂缝类型及产生机理,提出裂缝病害处置措施,以供参考。
Crack is one of the common diseases in road and bridge engineering.The generation and development of cracks will cause the decrease of structural integrity and durability.The cracks are not only large in number,but also have many causes.According to the road and bridge construction process,they can be divided into two parts:design cause and construction cause.The cracks caused by different causes need to be treated differently.Based on the analysis of the damage of road and bridge cracks,this paper analyzes the common types and causes of road and bridge cracks such as temperature difference cracks,settlement cracks and load cracks.Then,taking a new expressway in Guangdong Province as an example,through the investigation and research of crack diseases,combined with the types and generation mechanism of cracks existing in roads and bridges,the treatment measures of crack diseases are put forward for reference.
