盛土周辺地盤への変位抑制効果に着目した地盤改良について

抄録

A deep mixing stabilization method is often adopted as soft ground measures. For the purpose of cost reduction, the economical method is suggested, such as the floating type or low improved rate type. If we build road embankment on the soft ground at a near the house, in danger of a house inclining because the ground sinks. Therefore we need the new soft ground improvement method for the subsidence and displacement depression technique of the peripheral ground. In this report, we introduce the result of the centrifuge model test. Furthermore, we report measures effect of the road embankment on the soft ground. To obtain a satisfactory sideways flow preventive effect by effectively reinforcing the banking support ground by improving soil having a low improvement rate.
