ABSTRACT

Dynamic compaction replacement is an economical, simple and effective method for foundation reinforcement. Before construction, it is usually necessary to select typical test areas for experimental construction to determine its applicability and reinforcement effect, so as to guide large-area engineering construction. Especially, airport engineering has high requirements for roadbed settlement and uneven settlement, which meets the engineering quality. Under the premise of time limit and economy, it is particularly important to deal with soft soil foundation effectively. This discussion is based on the example of foundation reinforcement of Yanji Town in Ezhou, Hubei Province. Through the dynamic compaction replacement test in typical test area, the construction parameters are determined, and the rationality of dynamic compaction replacement method used in this kind of filling foundation is verified. At the same time, the special reinforcement effect caused by dynamic compaction replacement on the surface soil is studied.
