船舶行为分析模型在过闸船舶身份鉴别的应用

通过对京杭运河苏北段在航船舶的航行轨迹、航行速度、航行时间等船舶行为的分析,建立船舶的行为分析模型。对疑似虚假证照登记的船舶进行识别,将现有的核查方式变为有重点、有目标的核查,缩小了核查范围,提高了核查效率。     

基于电化学的有砟轨道路基病害整治研究

以某单线普速铁路路基为研究对象,通过调研路基现场设计室内试验,验证基于电化学的处理方法对路基排水设备损坏、路基沉降及翻浆冒泥三种病害的整治效果.结果 表明:电化学排水胶结对路基翻浆冒泥和基床下沉外挤病害整治有效且适用,提出了电化学排水胶结联合机械注浆封闭的铁路路基病害整治方法,并进一步探讨研究了该方法的施工工艺,得出了...

In-Situ Test on Fatigue Characteristics of Top-Mounted Dividable Pile-Board Subgrade for High-Speed Railway

To simulate the fatigue characteristics of the pile-board structure under long-term dynamic load, using the in-situ dynamic testing system DTS-1, the forced vibration loading was repeated one million times at different cross-sections of the pile-board structure for high-speed railway. The dynamic deformation, permanent deformation and dynamic stress of main reinforcements were measured. The test results show that the dynamic responses of the pile-board structure almost did not vary with the forced vibration...
