在铁路桥涵建设工程中,标准设计的使用率很高。中小桥和涵渠方面一般在90～95%左右,大桥设计也大部份采用标准设计。因此,大力整顿现有桥涵标准设计和广泛开展管理工作,将有重要的意义。从今年上半年来看,桥梁标准设计工作的开展是较为迅速、深入的。今年全路桥梁标准设计计划共30项,截至6月底已开工的有27项。质量方面也有了很大的提高,如一院修改圆形涵洞时发现了桥规的某些问题、在尖端形桥墩设计中对截面尺寸作了多方探讨;二院提出
In the construction of railway bridges and culverts, the standard design has a high utilization rate. Small bridges and culverts generally about 90 ~ 95%, most of the bridge design standard design. Therefore, to rectify the existing standard design of bridges and culverts and carry out extensive management work will be of great significance. From the first half of this year, the bridge standard design work is carried out more quickly and in-depth. This year a total of 30 standard bridge design projects, as of the end of June has started 27. Quality has also been greatly improved, such as a courtyard to modify the circular culvert found some of the problems of bridge gauge, pier design in the cutting edge of the cross-sectional dimensions made a multi-dimensional discussion; the second hospital
