Abstract：In order to reveal the settlement behaviors of high filled embankment and to predict the post-construction settlement，the long-term in-situ monitoring data of a certain high filled loess embankment were analyzed with the FEM computation and the method of layered iteration to inversely predict the post-construction settlement. The results show that the settlement of the embankment itself is the main part of the total settlement and accounts for 63% of the total settlement，while the original ground settlement accounts for 37%. The construction settlement is mainly caused by the compression of the pore air and exhaust consolidation. The uneven foundation and different heights are the main reasons of differential surface settlement.
