摘要
为满足铁路不断提速需求,适应技术标准变化特点,对天兰线某既有铁路桥梁工程进行了全面核查,通过对桥台的分析计算,主要控制情况为顺桥向的滑动稳定性、主要控制荷载为桥上无车、台后有车的情况.经对天水侧桥台进行加固处理等措施后,进行了梁体更换,使该桥满足规范[1,2]及提速要求,为以后类似工程提供了参考依据.
In order to satisfy the railway speed increase needs, and adaptation characteristics of change standardization techniques,we are verified the railway bridge engineering the existing of Tianshui-Lanzhou route roundly. Through the abutment were analyzed and calculated, the main condition is the no cars on bridge and cars have abutment behind about the sliding stability and load of straight the bridge direction. The side of Tianshui abutment is processed reinforcement, replacement of the beam,to meet standard requirement and increasing speed,its can also provide a reference for other engineering.
