Study on Centrifugal Modeling Test for Cut to Fill Subgrade Reinforced by Geogrid

With geotechnical centrifugal modeling test,the treating effect of different geogrid reinforcement schemes on uneven settlement at the cut to fill location of subgrade is studied.By means of measuring the deformation and displacement at the test point on the surface of such subgrade,what role of the paving layers of the geogrid can play to improve the uneven settlement of the cut to fill subgrade and the stability of subgrade as a whole is analyzed,as a result,the best treating scheme could be obtained according to the contrast tests.The test results show that,in connection with the uneven settlement of the cut to fill subgrade,the treating effect of two layers of geogrid is superior to one layer,while that of one layer is superior to none of geogrid.
