【摘要】 当前,各国高度重视国家交通网的立体化和多功能化问题,这主要是为在资源有限的前提下,尽可能将现有交通设施的效能最大化,从而在遭遇自然灾害或战争时能够承担迅速膨胀的运输需求。高速公路跑道最重要的意义在于其平战结合的特点。在平时,高速公路跑道作为普通高速公路使用,其跑道的“本质”在需要时可以迅速从储备状态转变为使用状态。由于公路跑道要同时兼备公路和跑道的两种特点,各种参数都需要综合考虑。本论文以“高速公路适应飞机起降参数研究”课题为依托,在文献调查的基础上,以对比分析和数值模拟为手段,对高速公路适应飞机起降的主要参数进行了系统的研究。总结了高速公路满足飞机跑道各控制参数的分析方法,根据各规范(规定)的要求,提出了新建及改建高速公路飞机跑道的部分净空参数和几何参数的建议值,利用有限元计算程序EverFE,分析了飞机荷载作用下典型水泥路面结构的应力响应和位移变化情况以及随路面结构变化的规律,利用专业程序Bisar,对飞机荷载作用下国内典型沥青路面结构的应力响应和位移变化规律进行研究。对高速公路跑道的修建工程有一定的参考价值。更多还原

【Abstract】 Nowadays, many countries pay attention to the Stereochemistry and multi functions of the transportation net, in order to make the best use of traffic facilities on the premise of resource-constrained, and meet the rapid expansion transportation needs in natural disaster and war times. Highway runway’s significance is the characteristics of combination of peacetime and wartime. It used as common road at peacetime, the essence of the runway is that it can rapidly change reserve condition into use condition. Because the characteristic of highway runway consist of the characteristic of road and runway, so every parameters should be considered synthetically.This paper is based on the subject of the parameter study that highway adapt to the rising and landing of airplane, with studying of many related research work publication, using comparative analysis and numerical simulation methods, research the parameter that highway adapt to the rising and landing of airplane systematically. The analysis method of control parameters that adapt to runway is summed up. Based on the code requirement, this paper puts forward the clearance and geometric parameters of the new and reconstruction highway runway. This paper use finite element program EverFE, analyse the conditions of the typical cement pavement structure stress response and displacement change and the variation regulation of the pavement structure under the airplane loading effect. This paper also use special program Bisar, analyse the conditions of the typical asphalt pavement structure stress response and displacement change regulation under the airplane loading effect. The conclusion of this article can provide references for the construction of the highway runway.更多还原
