| Analysis of subsidence behaviour of CFG (Cement Flyash Gravel ) composite subsoil on Beijing-Shanghai high-speed railway |
| 摘要 |
| 針對(duì)京滬高速鐵路典型地質(zhì)條件的CFG樁加固路段，采用FLAC3D有限差分程序，模擬路基的填筑過(guò)程，將樁和土按不同的材料考慮，計(jì)算CFG樁加固后路基的沉降，并與實(shí)測(cè)沉降比較，驗(yàn)證了計(jì)算模型的可行性。利用該模型分析了不同樁長(zhǎng)、樁間距對(duì)沉降的影響，并根據(jù)其路基沉降量，得到 |
