Abstract: Combined with the pre-construction geological conditions of the pile foundation of China Resources Power Plant (Bohai New Area), the economic and technical comprehensive comparison of the foundation plan was carried out through careful analysis, research and evaluation of the prototype test. The distribution law of the side resistance of the pile was analyzed, which could provide reasonable pile foundation bearing capacity, construction technology and construction parameters in the actual project. This research could provide guidance for construction of pile foundation, and also provide recommendation for the engineering detection and construction supervision.
