摘要
研究了最后进近及复飞阶段航空器与地面障碍物之间的碰撞风险的计算方法，结合航空资料汇编中上海虹桥机场的相关信息，利用碰撞风险模型对机场的主要障碍物进行了碰撞风险计算，并分析了障碍物宽度、障碍物高度、障碍物X位移和Y位移等四个参数的变化对碰撞风险的影响。结果表明虹桥机场的障碍物碰撞风险小于安全目标水平，超障高满足要求；在一定范围内，碰撞风险随障碍物高度增大而增加，但当宽度到一个临界值后不再增加；随障碍物宽度增大而增加；随X位移增大而减小；当Y位移为0时，碰撞风险值最大。
Abstract
This paper studies the calculation methods of collision risk between aircraft and ground obsta -cles in the final approach and missed approach phases , and by means of collision models calculates the collision risk for the major obstacles to the Shanghai Hongqiao Airport combined with the related AIP in-formation of Shanghai Hongqiao Airport .It includes analysis of impacts on collision risk of changes of the four parameters:the obstacle width,height,obstacle X displacement and Y displacement.The results showed that the collision risk of obstacles in Hongqiao Airport is less than the target level of safety , to meet the requirements of obstacle clearance height;within a certain range ,the collision risk increases with increasing height of the obstacle ,but till the width to a critical value;it increases with increasing obstacles width;it decreases with increasing X displacement;when Y displacement is 0 , the collision risk is the maximum value .
