【摘要】在我国目前的桥梁工程建造当中,其钢筋混凝土的桥梁则是作为最多的桥梁工程。然而,在钢筋混凝土的桥梁当中其裂缝问题则是最为多见的一种效应,也是最难防止发生的一种现象。因此,怎样可以避免和减少这种情况的发生是我们需要进一步研究和分析的。主要针对路桥施工当中的混凝土结构经常出现的裂缝问题,对此从材料、设计、施工以及荷载等诸多方面进行探讨,对于产生裂缝的各种原因进行分析,从而找出合理的预控措施,同时也提高了混凝土结构的耐久性。

【Abstract】In our current project to build a bridge among its reinforced concrete bridge is the bridge project as the largest. However, among its reinforced concrete bridge crack problem it is an effect of the most common and also the most difficult to prevent the occurrence of a phenomenon. Therefore, how to avoid and reduce the occurrence of this situation is that we need further research and analysis. Mainly for road and bridge construction cracks in concrete structures which often appear, which were from the material, design, construction and other loads and investigate many aspects, for various reasons, cracks were analyzed in order to identify a reasonable pre-control measures, also improve the durability of concrete structures.

当前,我国交通建设在随着迅猛的发展,而路桥建设也在不断的增多,但在不同类型的路桥施工当中,其混凝土结构的应用则是越来越广泛,并且在路桥的施工过程当中已经占据了很大的一部分,得到了广泛的使用。由于在路桥的施工当中,这种结构的特点就是施工方便、装饰性较强、价廉物美,并且承载力较大等一些优势,但是,在应用混凝土结构的同时也会存在一些问题,由于没有充分的了解混凝土的一些主要性能,所以施工结束后,其结构便会出现裂缝等一些不良反应,在一定程度上也带来了不便,虽然在施工当中会应用各种不同的措施进行预防,但这种现象仍会时有出现,同时也造成了一定的经济损失。对此,研究人员为了可以控制和降低裂缝的产生,都对此做了大量的实验研究,从而提出了一些相应的解决措施,并把混凝土裂缝问题控制在最小的范围里。……
