吹填珊瑚砂机场跑道地基处理方法研究

Study on Foundation Treatment of Airport Runway with Dredged Coral Sand

马尔代夫维拉纳国际机场改扩建工程飞行区场地采用吹填珊瑚砂填海造陆而成。根据珊瑚砂工程特性和飞行区地基受力特性,确定了地基处理方法和处理深度。通过地基处理小区试验,确定了地基处理施工工艺和参数,形成了吹填珊瑚砂机场跑道地基处理技术和检测方法。

In the course of the reconstruction and expansion of the Velana International Airport in the Maldives,coral sands were used to carry out the dredging of the flying area sites to fill the land.The depth of foundation treatment is determined according to the demand for the mechanical characteristics of the foundation in the flying area and the requirements for the bearing capacity,deformation and pavement structure of the runway foundation of the airport.Through the experiment of ground treatment area,the impact rolling and vibration rolling treatment methods and different vibration parameters are compared.Finally,the method of foundation treatment and detection of the airport runway filled with coral sand is formed,which provides a guarantee for the smooth development of the foundation treatment work in the flying area.
