| 季節(jié)凍土區(qū)鐵路路基變形監(jiān)測及凍害原因分析(50 卷) |
| 英文標題 |
| Deformation monitoring of railway subgrade in seasonal frozen soil region and cause analysis of frost damage |
| 摘要 |
| 根據京包鐵路、包蘭鐵路路基在1月—6月期間的變形監(jiān)測和路基土的級配試驗，分析了季節(jié)凍土區(qū)鐵路路基的凍脹變形情況及產生原因。分析結果表明，在內蒙古境內的季節(jié)凍土區(qū)鐵路路基凍脹呈現整體性變形特點，但不同里程處的路基凍脹差異較大；在監(jiān)測區(qū)段內，京包線路基最大凍脹 |
