Abstract
Using the large-scale finite element analysis software ABAQUS,the overall modeling and analysis of the circular coal yard structure and surrounding soil with underlying inclined bedrock were carried out.To reduce computational complexity,two semi coal pile loading conditions which the coal stacking direction is the same or perpendicular to the inclination direction of the bedrock are considered with wind loads in the same direction to form unfavorable combinations.The results show that the underlying inclined bedrock will cause a downward sliding trend along the inclined bedrock in the circular coal yard.Combined with the distribution of semi coal pile load,the internal force and deformation distribution of the circular coal yard are uneven.The foundation of the coal retaining wall in the filling area adopts pile foundation.High stiffness of short piles will cause stress concentration phenomenon,which should be avoided in the design.C15 concrete can be used for transition at the junction of the excavation and filling areas.When combining the internal forces under a single operating condition for design,the reinforcement of the annular bearing platform and coal retaining wall is calculated as eccentric tension members in the circumferential direction,and the reinforcement of the coal retaining wall is calculated as eccentric compression members in the vertical direction.关键词
