机场跑道宽度可靠性设计方法研究

 为适应现代航空器的发展，更加合理地设计机场跑道平面尺寸，对跑道宽度设计问题进行系统研究。依据飞机着陆过程侧向偏移量的计算公式，将可靠性理论引入到跑道宽度的设计中，弥补了以往仅依靠飞行要求和经验来确定跑道宽度的不足。对某地多年气象资料统计分析和飞机着陆轮迹横向分布规律实测分析，结果表明：跑道侧风去除部分静风后服从极值I 分布，着陆轮迹服从正态分布。基于蒙特卡洛法，通过matlab 软件分别计算不同失效概率所需的跑道宽度，并对现有跑道宽度进行了可靠性评价。计算结果表明，跑道宽度对空气相对密度变化不敏感，现有跑道宽度的理论失效概率与实际失效概率比较接近，具有较大实际意义。

Research on Reliability Design Method of Airport Runway Width

In order to adapt to the development of modern aircraft and design the dimension of airport runway more reasonably, the problem of airport runway width is studied systematically. A computing method of the plane's basic demand for the airport runway width is elaborated. The theory of reliability is drawn into the design of runway width, which makes up for the deficiency of just relying on the flying requirement and experience to design the width. Based on the statistical analysis of meteorological data and transverse distribution of aircraft landing marks of a airport, the crosswind without a part of 0 wind is subject to the extreme I type distribution and landing marks are subject to normal distribution. According to the Monte Carlo method, the runway width is calculated under different failure probabilities by Matlab, followed by the reliability evaluation of the present runway width. The result shows that the runway width isn't sensitive to the change of air density and the theoretic failure probability is close to the actual failure probability, which is practically significant.
