As a new type of backfill material for abutment back treatment, there is still a gap in theoretical research and practical application. Aiming at the research on the treatment effect of the new backfill material liquid soil, this paper uses the finite element software for numerical simulation, comprehensively compares and analyzes the settlement and deformation characteristics of the new backfill material liquid soil and the conventional soil under the same working condition, and evaluates the treatment effect according to the calculation results; The results show that under the action of self weight load and traffic load, the overall settlement of both sides presents a similar distribution. In the horizontal direction, the settlement gradually increases from the near platform back to the far platform back. In the vertical direction, the settlement first increases and then decreases. Moreover, the road settlement under the action of vehicle load is larger than that under the action of self weight load only. However, the settlement of liquid soil backfill is far less than that of conventional soil backfill. Using liquid soil as backfill material can reduce the harm and economic loss caused by settlement to a certain extent.
