Settlement Behavior of Highway Transition Sections on Soft Clay Foundation
When highways were constructed on the soft clay foundations, the ground improvement methods such as deep mixing column, preloading and gravel column, were alternately used, and the transition sections were generated. When the different settlement between two methods was large enough after operations, the crack or bumping on the pavement probably happened. In the paper, a transition case between the preloading method and the deep mixing method was studied. Later the three dimension finite element method (3DFEM) was adopted to analyze its different settlement behavior. The results showed that the different settlement just happened in a small zone near the border of two ground improvement methods instead of the whole transitional zone.
