A Solution to Remove Railway Track Discontinuities at Spiral Junctions [PDF]
International Journal of Mechanical Engineering and Applications, 2020 To design railway track layouts, engineers use tangent and circle segments. To maintain curvature and bank angle continuities between flat straight lines, with zero curvature, and banked circles, they use spiral segments where curvature and bank angle vary linearly as function of distance.

Method for calculating seismic active earth pressures on cantilever retaining walls
Yantu gongcheng xuebao, 2023 In order to determine the seismic active earth pressures on the stem of a cantilever wall, the resultant of the earth pressures on the assumed plane wall back is firstly derived using the upper-bound limit analysis and the pseudo-static method for five ...

Research on the Deformation Mechanism of Railway Subgrade under Buried Strike–Slip Fault Dislocation
Applied SciencesWith the gradual densification of China’s railway network, more and more railways are inevitably crossing active fault zones. Creep dislocation and stick–slip dislocation of the fault zones can lead to uneven deformation and cracks in the railway ...

Evaluating health effects of transport interventions: methodologic case study [PDF]
, 2006 Background: There is little evidence about the effects of environmental interventions on population levels of physical activity. Major transport projects may promote or discourage physical activity in the form of walking and cycling, but researching the ...
