摘　　要：针对侧向跑道相关运行模式下航空器进离场安全间隔问题进行碰撞风险评估。为保证航空器之间的安全运行,对机场侧向跑道运行模式进行分析,计算两跑道航空器之间的动态间隔,并考虑导航误差、速度误差等因素建立位置误差碰撞风险模型。以成都天府机场侧向跑道为例,利用MATLAB软件对航空器间的碰撞风险进行仿真,并进一步得到碰撞风险值与侧向跑道汇聚交叉角度的关系。仿真结果表明:在起降相关运行模式下,当终端区航空器起始水平间隔距离为6 km,侧向跑道交叉角度为90°时,总的碰撞风险为5.14×10^(-9),满足航空器之间安全水平要求,且随着侧向跑道汇聚交叉角的增大,跑道上两架航空器的碰撞风险逐渐减小。The collision risk assessment is carried out for the safe interval between aircraft approach and departure in the lateral runway related operation mode.In order to ensure the safe operation between aircraft,the lateral runway operation mode is analysed,the dynamic interval between aircraft on the two runways is calculated,and the position error collision risk model is established by considering the navigation error,speed error and other factors.Taking the lateral runway of Chengdu Tianfu Airport as an example,MATLAB software is used to simulate the collision risk between aircraft and further obtain the relationship between the collision risk value and the converging crossing angle of the lateral runway.The simulation results show that under the landing and take off related operation mode,when the starting horizontal separation distance of aircraft in the terminal area is 6 km and the lateral runway crossover angle is 90°,the total collision risk is 5.14×10^(-9),which meets the safety level requirement between aircrafts,and the collision risk of two aircrafts on the runway gradually decreases with the increase of the lateral runway convergence crossover angle.
