Experimental study on dynamic characteristics of sand in Fuzhou Airport
摘要
Abstract
Site stability determination is of great significance to ensure the long-term safety and stable service of airports.The dynamic properties and influencing factors of the saturated sandy soil of Fuzhou Airport are investigated by using the dynamic triaxial tests,and the site liquefaction resistance is discriminated by the indoor and field tests.The results show that the dynamic shear modulus ratio of the sandy soil increases with the increase of the enclosing pressure,the damping ratio decreases with the increase of the enclosing pressure,and the dynamic strength of the soil increases with the increase of the enclosing pressure.The two site liquefaction discrimination methods have good consistency at depths less than 8 m,which verifies the feasibility of the indoor tests to determine site stability.关键词
