| Treatment of frost heave defects occurred in subgrade above railway culvert by horizontal pipe drain with laying of EPS (Expanded Polystyrene Slab) |
| 摘要 |
| 路基凍脹是北方鐵路工程常見的病害之一，對于路堤地段最有效的辦法是換土進(jìn)行徹底整治，但對京哈線（秦沈段）發(fā)生在涵上填土部分的路基凍脹采用換土的方法對既有鐵路運輸影響較大。通過反復(fù)研究和現(xiàn)場試驗，決定采取平孔排水結(jié)合涵頂板鋪設(shè)EPS保溫板的方法進(jìn)行整治，達(dá)到了通 |
