| Abstract: | Based on various design schemes of cement mixing piles composite foundation for the track girder of stacker-reclaimed in one ore stockyard, we use P1AXIS2D numerical model to analyze the law of horizontal displacement and axial stress for the cement mixing piles, the distribution law of strain for the composite foundation under 250 kPa load, then put forward relevant suggestions on the loading plan in the period of stockyard use, which will provide necessary reference for the operation of similar projects. |
