摘　　要：机场运行指标的重要组成部分包括机场净空安全管理,所以控制障碍物高度是机场净空管理中重要的工作之一,现阶段ICAO标准下的障碍物评价面(OAS)较为保守,空域利用率低。在碰撞风险模型(CRM)椭圆评价面的基础上构建切面模型优化OAS面,将优化前后的OAS面进行比较,优化后的OAS面的空域限制比原有OAS面宽松,模拟障碍物计算碰撞概率满足OAS面上每点碰撞概率远小于1×10^(-7),满足目标安全水平,对双流机场实际运行有一定参考价值。Airport clearance safety management is an important part of airport operation indicators.Controlling the height of obstacles is one of the most important tasks in airport clearance management.At this stage,the obstacle evaluation surface(OAS)under the ICAO standards of Shuangliu Airport is relatively conservative,and the airspace utilization rate is relatively conservative.On the basis of the collision risk model(CRM)ellipse evaluation surface,a cross section model is constructed to optimize the OAS surface,and the OAS surface before and after optimization is compared.The airspace restriction of the optimized OAS surface is looser than the original OAS surface,and the collision probability is calculated by simulating obstacles.The collision probability of each point on the OAS surface is far less than 1×10^(-7),and the target safety level is met,which has certain reference value for actual operation.
