250M长钢轨回收车收轨装置
收轨装置 钢轨回收车
2008/11/19
铁路提速适应了国民经济发展的需要，铺设无缝线路是铁路提速的重要基础工作，但是铺设无缝线路时，替换下来的旧钢轨被置于线路股道中心，给行车安全带来隐患，因此需及时回收旧钢轨。该型钢轨回收车由机车、承轨车、作业车及收轨装置等组成，采用双收轨小车，增加了钢轨在提升过渡区的支撑点，提高了钢轨输送的稳定性；新型双体输轨梭头通过滑块联接可相对移动，满足了在曲线地段收轨作业的使用要求；应用变频高速的电动滚筒辅助推...

随着中国城市建设的快速发展，地铁作为缓解城市交通紧张的有效工具在北京、上海、广州、天津几个大城市已投入运营，深圳、重庆、大连等十几座城市也正在或准备建设地铁系统。然而，地铁的安全问题不容忽视，尤其是火灾事故已严重威胁到地铁的运行安全。由于地铁运行在地下，出入口少、通道狭窄、电气设备又常处于饱和状态，所以地铁车辆具有较高的火灾危险性。同时，地铁又是一个人员高度密集的公共场所，人员疏散条件差，一旦发生...
下穿大型铁路站场的地铁车站施工对线路变形影响的监测分析
地铁隧道工程 下穿既有铁路站场 矿山法 线路沉降监测
2008/4/21
受南京铁路站场的制约，地铁南京站主体结构被分割为南侧明挖区、过站区和北侧明挖区等三个部分，过站区在既有南京铁路站场下方，其结构型式为双线分离式隧道，隧道跨度大、埋深浅、线间距小，采用暗挖矿山法构筑。在既有铁路线下修建地铁车站，必须严格控制线路沉降。通过在地表线路和便梁支墩上布置沉降测点并跟踪施工进程进行监测，探讨地铁过站隧道施工对地表线路变形的影响。监测结果表明：铁路线路加固措施和过站隧道施工方案...

青藏铁路安多试验段斜坡路基地温及变形特征分析
地温 人为上限 水平位移 沉降
2007/7/20
通过分析青藏铁路安多试验段斜坡路基三个冻融周期的地温和变形监测资料，发现其人为上限有一定程度抬升（除阳坡坡脚外），并表现为阴阳坡不对称；对比监测期内原天然上限位置和原地面位置的地温值，相应位置的地温逐年降低，路基逐年趋于热稳定；而从变形特征来看，无论是路基的水平位移还是竖向沉降，其量值逐年增大，但发展水平逐年降低，路基的变形也在逐渐趋于稳定。由此看来，按照现今设计方案，安多斜坡路基是合理可靠的。
