| 鄭西線濕陷性黃土地區(qū)橋梁基樁負(fù)摩阻力計算探討(37 卷) |
| 英文標(biāo)題 |
| Discussion on the Computation of Negative Frictions of Bridge Pile Foundation in Collapsible Loess Area Along Zhengzhou-Xi’an Passenger Dedicated Railway |
| 摘要 |
| 鄭西客運(yùn)專線經(jīng)過三門峽至靈寶濕陷性黃土地區(qū)，橋梁基樁穿過濕陷性黃土承載力計算必須考慮負(fù)摩阻力。通過采用國內(nèi)2種規(guī)范負(fù)摩阻力計算方法，對工程實(shí)例進(jìn)行計算，以及對基樁穿過濕陷性黃土浸水載荷試驗實(shí)測過程中負(fù)摩阻力變化規(guī)律、中性點(diǎn)變化規(guī)律、樁側(cè)摩阻力發(fā)揮情況的分析 |
