Abstract
A combined technology of shallow stabilization and floating-type deep mixing wall has been developed as method with acceptable settlement for maintaining the function of the high standard roads or high embankments on soft ground. As for this method, shallow stabilized ground has relatively low bending strength and shows very brittle behavior. Therefore it is important to evaluate bending stress acting on the shallow stabilized ground in considering distribution of subgrade reaction from deep soil stabilization portion. In this paper, at first, in order to evaluate bending stress of shallow stabilized ground with floating type deep mixing wall under uniform vertical stress conditions, bending stress model is proposed based on the idea of stress distribution ratio in relation to the skin friction applied around the surface of the deep mixing wall. In order to confirm the validity of this proposed model, loading model test of the improved ground was performed using loading device for applying uniform vertical stress corresponding embankment load. Finally, the validity of the calculated values obtained from this proposed model was confirmed from the results of full scale analysis.
