我国部分铁路预应力混凝土桥梁和轨枕始终存在着与译文介绍内容相似的病害问题，而在病害原因的验证以及受病害影响的桥梁、轨枕的损伤分级和处理方面，我国均未建立起一套有效的分析方法。但因加拿大与我国运输条件不尽相同，因此仅希望在本文的启发下能结合我国混凝土桥梁及轨枕的病害情况，亦进行相应的试验研究工作。 In our country, some railway prestressed concrete bridges and sleepers always have the same disease problems as the ones described in the translation. However, none of our country has established a set of effective measures to verify the cause of disease and the damage classification and treatment of bridges and sleepers affected by diseases Analysis method. However, due to the different transport conditions between Canada and China, it is only hoped that this paper will be able to combine with the concrete bridges and sleepers disease conditions in China, also carried out the corresponding experimental research.
