Abstract:Aiming at the problem that abnormal conditions such as the difficulty for foundation piles to be penetrated into the designed height and affect the construction under complex geological conditions,the drivability of foundation piles and the quality control methods of the pile sinking process are studied. Based on the reconstruction and expansion project of Dares Salaam Port in Tanzania,the method of conducting a comparative analysis of the GRLWEAP driveability and the whole-process PDA during the pile-sinking process of the pile foundation at the typical geological boreholes is adopted. And the conclusion is that the whole-process PDA results can be used to make more realistic corrections to the soil parameters in the driveability analysis. The research results show that the GRLWEAP driveability analysis after adjustment coucerning similar soil layer parameter correction values and the whole-process PDA can not only provide theoretical support for PHC piles sinking construction but also monitor the piles sinking process in real time for quality control.
