| 摘要： | This paper combines the results of field trials to study the adoption of a raft CFG pile composite foundation working traits on a flexible foundation.This test study on the contents of the piles and the soil between the piles at top surface of the CFG pile,the relative deformation at top of the foundation on condition of stacking load,the pressure value of pile top and soils between them,the variation of groundwater level and pore water as well as the horizontal displacement of testing point accordance with depth.The results of the study can provide the measured value for parameters in.designing of the CFG pile raft composite foundation under China's high-speed railway embankment. |
