Abstract: The alignment of track line on bridge will change with the displacement of bridge pier and subgrade. When the alignment changes seriously, it will endanger the traffic safety. Accurately predicting the influence of bridge pier displacement and subgrade displacement on track alignment is conducive to monitoring the line status and ensuring the safe operation of existing lines. In this paper, an intelligent information system for high-speed railway alignment is developed, which can calculate the alignment change according to the displacement change of pier and subgrade, predict and control the track alignment well, and facilitate the management of track maintenance personnel. This paper introduces the development principle of the system and the usage method of small program and web page.
Keywords: high speed railway adjacent line construction monitoring; alignment prediction; intelligent management; software development

当轨道线路的下部结构即桥墩或路基发生位移变化时,不可避免地会对轨道线路产生影响,严重时会对行车安全产生危害,因此必须对下部结构的位移进行监测与控制,同时对铁路轨道状态进行实时评价。目前我国现行的规范[1]中对于高速铁路轨道状态的评价均是通过测量轨道线形即几何不平顺值来确定的,但现有的监测手段无法实时监测高速铁路线路轨道结构的几何状态,只能通过监测桥墩墩台、路基等其他结构沉降进行间接测量。因此,准确地监测桥墩、路基等轨道下部结构位移同时间接计算轨道线性变化对于保障既有线路的安全运行具有重要的意义。然而由于间接计算过程较为复杂,现场难以进行计算控制,这为工务人员进行线形的管理与预测带来了极大的挑战。为简化计算流程,方便高效地得到钢轨线形随下部结构的位移变化而变化的规律及计算结果,本文开发了一套高铁线形智能化信息系统。……
