Study on Fundamental Frequency of Runway based on Winkler Model

摘要：

　　The change mechanisms of fundamental frequency of runway under different conditions are discussed in this paper.A full scale cement concrete slab finite element model is built to analyze the relationship between foundation modulus and the fundamental frequency of runway.The results show that the coupling effect of runway plates can not be neglected.The minimum area affecting the fundamental frequency of runway is 45m in longitudinal and 15m in transversal according to the analysis of fundamental frequency of different size runway.The fundamental frequency of runway ranges from 7.5Hz to 23.6 Hz when the foundation modulus increases.
