Abstract: Based on the structural characteristics of the ground-based radar，a brief mechanics analysis of the ground-based radar during railroad transportation is carried out in this paper．According to Railroad Cargo Loading and Reinforcement Rules，a reinforcement project is designed and the selection of the error-prone parameters is explained and standardized．In wind resistance calculation，the additional pressure caused when two trucks meet is considered，then the effect on reinforcement of the vertical and transverse tensile value change caused by the different binding site selection is analyzed and compared．After that，a method is proposed to amend the formula．This result shows that the method can improve the speed-up railroad transportation safety and can provide a reference for engineering．
