The persistent issue of moisture-induced "heave" in synthetic sports surfaces can affect athlete safety and surface performance. The objective of the study was to design an innovative synthetic material athletic track structure that mitigates adhesive failure between the synthetic layer and the cement base due to underground moisture. The new structure ensures field safety and meets biomechanical requirements for performance and shock absorption. Numerical simulation methods are employed to analyze the shock absorption performance of the synthetic material track and field facility, incorporating the new structure, and subsequently to propose optimization strategies for the structural design. The optimal structure adopted a circular casting hole design, with a cast-in-situ surface layer thickness of 12 mm, a prefabricated surface layer thickness of 6 mm, a hole diameter of 45 mm, and a hole spacing of 80 mm arranged in a square pattern. The results indicated that the proposed structure not only met the required standards for shock absorption, but also offered a promising solution to the issue of moisture-induced "heave" prevalent in traditional sports surfaces. The study provided important theoretical support and practical guidance for the scientific and efficient construction of athletic tracks.
合成运动场地中持续存在的由水分引起的“隆起”问题会影响运动员安全和场地性能。本研究的目的是设计一种创新的合成材料田径跑道结构，以减轻由于地下水分导致的合成层与水泥基层之间的粘结失效。新结构确保了场地安全，并满足了性能和减震方面的生物力学要求。采用数值模拟方法分析了采用新结构的合成材料田径设施的减震性能，随后提出了结构设计的优化策略。优化结构采用圆形浇筑孔设计，现浇表层厚度为12毫米，预制表层厚度为6毫米，孔径为45毫米，孔间距为80毫米，呈正方形排列。结果表明，所提出的结构不仅满足了减震的要求标准，而且为传统运动场地普遍存在的水分引起的“隆起”问题提供了一个有前景的解决方案。该研究为田径跑道的科学高效建设提供了重要的理论支持和实践指导。
