建国以来,我国的桥梁建设得到了很快的发展,数以万计的桥梁让天堑成了通途。然而,在众多已建成的桥梁当中,有不少桥梁出现承载力不足的现象。造成这种状况的原因很多,如:老旧桥原设计标准低,不能适应现时的交通流量及车型变化;公路改造时桥梁未能同步改造,以致于“路新桥旧”;建桥材料、施工质量;缺乏对桥梁维护的重视……等等。但不管怎样,这些出现问题的桥梁如不及时维护、补强、加固,必将影响我国的交通状况,造成交通隐患,甚而造成人民生命财产的损失。《OVM 通讯》本期发表了柳州市建筑机械总厂在旧桥加固方面的两篇文章,以期能带给同类工程提供一些借鉴。
Since the founding of the People’s Republic of China, the bridge construction in our country has been rapidly developed. Tens of thousands of bridges have made natural moat a thoroughfare. However, among the many completed bridges, there are many bridges that have insufficient capacity. There are many reasons for this situation. For example, the original design standard of the old bridge is low and can not meet the current traffic flow and vehicle type changes. The bridge can not be reconstructed synchronously when the highway is rebuilt, so that the old road, Materials, construction quality; lack of emphasis on bridge maintenance ... and so on. In any event, failure to maintain, reinforce and reinforce these bridges that have emerged will inevitably affect the traffic conditions in our country, causing traffic problems and even causing losses to people’s lives and property. This issue of OVM Newsletter published two articles on the strengthening of old bridges in Liuzhou Construction Machinery Plant with a view to providing some references for similar projects.
