%X Based on the project of high-embankment widening of highway,the water content and degree of compaction of foundation soil,filling and improved soil by lime were determined by means of indoor physico-mechanical test.The centrifugal modeling tests were used to simulate increasing degree of compaction and improve soil by lime for coordinating deformation between new and old high-embankment widening.The test results show that the deformation of high-embankment widening was decreased,but differential settlement was not controlled effectively when the degree of compaction of high-embankment widening was increased to 93%,94% and 96% from 90%,93% and 95% correspondingly.Then both deformation of high-embankment widening and differential settlement were decreased when the filling was improved by 6% lime mixture;and the effects of deformation compatibility of high-embankment widening were enhanced.The in-situ monitoring data agree well with the results of centrifugal modeling test.
