| Study on defects of construction quality and technology of prevention and control for CFG (Cement Flyash Gravel) piles on passenger-dedicated railway |
| 摘要 |
| 結(jié)合京石鐵路客運(yùn)專線工程實(shí)際進(jìn)行了CFG樁復(fù)合地基處理軟土地基技術(shù)研究。通過分析施工過程中堵管、竄孔、混凝土超用量、抱鉆、樁頭空芯、樁端不飽滿、斷樁等質(zhì)量病害產(chǎn)生的原因，提出了施工質(zhì)量控制措施，確保了CFG樁復(fù)合地基的處理效果。 |
