| 道床縱向阻力變化對無縫道岔受力與變形的影響(50 卷) |
| 英文標(biāo)題 |
| Influence of change of subgrade bed longitudinal resistance on stress and strain in continuous welded turnout |
| 摘要 |
| 為了進(jìn)一步研究無縫道岔受力和變形的特點(diǎn)，通過建立模型，利用現(xiàn)場實(shí)測數(shù)據(jù)，計(jì)算了道岔直側(cè)股、道床搗固前后、岔區(qū)與區(qū)間線路的道床縱向阻力。計(jì)算得到12號道岔鋼軌升溫50℃時(shí)各部分的受力和變形結(jié)果。分析表明：直側(cè)股道床縱向阻力相差越大，直曲基本軌處限位器作用力大小 |
