| 京滬高速鐵路CFG樁復(fù)合地基沉降預(yù)測(cè)分析(49 卷) |
| 英文標(biāo)題 |
| Prediction analysis on settlement of CFG pile composite foundation for Beijing-Shanghai high speed railway |
| 摘要 |
| 在京滬高速鐵路鳳陽試驗(yàn)段現(xiàn)場試驗(yàn)的基礎(chǔ)上，獲得了CFG樁復(fù)合地基實(shí)測(cè)沉降數(shù)據(jù)。在實(shí)測(cè)沉降數(shù)據(jù)的基礎(chǔ)上對(duì)路基沉降預(yù)測(cè)問題作了進(jìn)一步的探討，采用了4種曲線擬合法對(duì)路基沉降進(jìn)行了預(yù)測(cè)分析及對(duì)比研究。結(jié)果表明：曲線擬合法的預(yù)測(cè)精度取決于映射函數(shù)和實(shí)測(cè)沉降樣本空間范圍 |
