Abstract:To the transformation of coal,ore and other bulk cargo yards into fully automated container yard,with varying load sizes and stacking times in different regions,resulting in significant differences in site conditions,a study is conducted on the settlement calculation of the foundation to meet the requirements for the use of fully automated container yards.The study adopts the layer-wise summation method,the settlement calculation method considering stress history,and the stress area method for settlement analysis,and considers the location,stratigraphic distribution,and previous stacking load,stacking service life,and other conditions for each hole.The results indicate that in the foundation renovation of the yard,the settlement calculation method considering stress history under uniform load conditions provides a more accurate representation of actual conditions.The application of the settlement calculation method considering stress history under uniform load conditions to calculate the foundation settlement of the renovated yard has good guiding significance,and can provide reference for the foundation design of automated container yards in yard renovation.
