| 摘 要： | 改建铁路包兰线(银川至中卫段)提速扩能改造工程设计行车速度为200km/h,由于既有铁路新增二线控制因素较多,桥涵设计相对复杂,要求我们必须做到综合考虑分析问题.通过对既有线上的桥涵调查分析,结合既有桥涵存在的实际问题,本着充分利用既有桥涵,避免大拆大改的原则,提出相应的既有线改建方案.

| Abstract: | The design running speed of upgrading project of Yinchuan-Zhongwei Section on reconstructing railway from Baotou to Lanzhou is 200km per hour.Because of many controlling factors,the design of bridges & culverts on the additional 2nd line to the existing line is comparatively complicated.So we must have a integrate consideration.The writer,in conformity with the principle of making full use of existing bridges & culverts to avoid overhaul,through combining analysis of investigations on existing bridges and c... |
