Abstract: The long-term and transient deformation characteristics of soft soil ground under explosive loading are analyzed through the field test and numerical simulation. The main factors affecting explosion results and the remarkably impact range in the soil after explosion are investigated. Mechanism of improving soft ground by explosion is discussed. The results show that this method can accelerate consolidation speed, improve the construction speed and shorten the time limit for a project.
