Abstract

ABSTRACT Safe runway pavements are essential for the smooth landing of aircraft. Due to aircraft movements, these pavements are subjected to large dynamic loads that can cause their failure and jeopardise safety. This paper proposes the use of improved cement-based layers to enhance the performance of flexible runway pavements. The performance of such retrofitted runway pavements under both static and moving loads is investigated by experimental study and three-dimensional numerical simulations. Results indicate that the improved cement-based layers can significantly reduce surface deflections in the runways under heavy static and moving loads. Under heavy moving loads, the proposed cement-based layers can distribute the vertical stresses to the surrounding soil area, significantly reduce surface deformations and prevent failure. Findings of this research will contribute towards improved designs of runway pavements resulting in enhanced safety and failure mitigation.
飞机载荷作用下改进型柔性跑道路面性能评价
安全的跑道路面对于飞机的平稳降落至关重要。由于飞机的运动,这些路面受到巨大的动载荷,可能导致其失效并危及安全。本文提出采用改良水泥基层来提高柔性跑道路面的性能。采用试验研究和三维数值模拟的方法,研究了这种改型跑道路面在静、动载荷作用下的性能。结果表明,改进后的水泥基层能显著降低静、动载荷作用下的跑道表面挠度。在较大的移动荷载作用下,所提出的水泥基层可以将竖向应力分布到周围土体区域,显著减少地表变形,防止破坏。这项研究的结果将有助于改善跑道路面的设计,从而提高安全性和减少故障。
