| 摘 要： | 攀钢新基地工程区80%为"昔格达"土回填区,回填土将对桩产生负摩阻力。现场负摩阻力试验表明:回填土上部在堆载情况下会有较大的固结沉降,从而使桩基产生负摩阻力。 |

| Abstract: | The 80% of engineering area of Pangang new base is the backfill field of ＂Xigeda＂ soil,which results in negative friction resistance to the pile.The negative friction resistance experiment on the spot shows that there is more consolidation sinking under the accumulation load of upper backfill soil,which can cause negative friction resistance to the pile. |
| Keywords: | ＂Xigeda＂ Uncompleted Consolidation Soil Negative Friction Resistance Experiment on the Spot Rotation Dredge Pile Pangang Group of Sichuan |
