Abstract

Abstract

The bearing capacity characteristics and internal force distribution of transmission digging foundation with plumb and batter angle foundations under inclined loads are studied using extensive numerical modeling.The results reveal that the vertical bearing capacity of plumb foundations are changed less under the load inclination less than 10,while the vertical bearing capacity remarkably decreases when the load inclination is greater than 10.The vertical bearing capacity of foundation with positive batter angles is greater than the vertical and negative batter angles under the same inclined loading,meanwhile,the bending moment and shear force of foundation with positive batter angles are the less than the negative batter angles.In case of foundation batter angles are same with the load inclination proved to be the best configurations,the vertical bearing capacity is not decreased,on the other hand,the bending moment of this configuration is almost zero.
