Laboratory Experimental Study on the Composite Ground under High Road Embankment

A simple laboratory model experiment about composite ground under flexible foundation has been done.Soil is used to simulate the soft ground and clay mixed with some cements used to simulate the embankment.Taking the plane strain characteristics and the pile group effect into consideration,the experimental model can be gained by means of the three rows of piles continuously distributing under the flexible embankment.The P-S Curve is recorded by the extensometer and the displacement field of the composite ground is also gained by the soil line and the displacement observing points.Some qualitative analysis from the point of the settlement and deformation about the composite ground under flexible foundation is executed and some regularity is obtained in this paper.
