摘要
通过实验段CFG桩施工过程中旧路路表变形的监测,结合类似工程中超静孔隙水压力累计及消散规律,分析振动沉管CFG桩施工导致的土体变形对旧路产生的扰动影响,所得出的结论对类似工程具有一定的参考价值。
Through the deformation of the old road surface monitoring in the CFG pile construction of experimental section,combined with the accumulation and dissipation laws of excess pore water pressure in the similar project,Disturbing effect on the old road produced by soil deformation caused by the CFG pile construction of vibration diving casting is analyzed.The conclusions have some reference value on the similar projects.
