Numerical Analysis on Settlement Law of High Soil-Rock Aggregate Mixture Embankment under Traffic Loads
摘要
Abstract
High soil-rock aggregate mixture embankment is one of the subgrade forms used in construction of highway in mountainous area. The control of the post-construction settlement has become a trouble therein. The dynamic model for the high embankment under traffic loads is established to carry out numerical simulation by finite element software ANSYS, through which the settlement law of the high embankment under three-lanes and three-car traffic loads at the speed of 100 km/h is studied ; and the relationship between the settlement and the number of cycles of the embankment under such load. As a result, the basis could be offered for the measures controlling settlement in construction.关键词
