Bored concrete pile design in deep backfill of Shengyuan freight station
CHANG Jie-yun
Abstract：Shengyuan freight station is not only a key part of the coal distribution links,but also the road concentration and rail transport of the intermediate links.Civil structure is the carrier of the various transport links in the system and the prerequisite for the operation of various equipment.As the project is located in the valley backfill area,backfill thickness is more than 20m,which is not suitable for building constructions,in order to ensure the project progress,we decide to use socketed piles which penetrate the backfill area.In order to determine the proper calculation methods for the actual conditions of the end bearing friction pile and the rock socketed pile,we calculate and analyze the bearing capacity difference of trestle legs using two calculation models.According to the results of theoretical analysis and static pressure test,it is concluded that the end bearing friction pile is more suitable for the actual working condition of the project.
