WebJul 8, 2024 · Track buckling is formation of large lateral misalignments in continuous welded rail (CWR) track, often resulting in catastrophic derailments. Both curved and tangent tracks are susceptible to buckling with typical curve buckle amplitudes ranging from 6"-14" and tangent buckles from 12"-28". Buckles are typically caused by a combination …
WebMay 1, 2024 · It seems likely that the shaft resistance along the pile affects the buckling of the friction piles. There only exists a few solutions that take into account shaft friction of the pile-soil system. These have been done for straight friction piles by using the energy method [14], Rayleigh-Ritz method [15] and modal clustering technique [16].
