摘　　要：机场高填方边坡工程竣工后可能出现沉降、不均匀沉降等现象。在实际工程中,由于场区条件复杂、土体参数多样、填方高度不一,机场高填方边坡沉降稳定控制以经验为主,控制效果不佳。文章依托ABAQUS建立数值仿真模型,进一步研究不同干密度和泊松比下的工后沉降速率,为机场高填方沉降稳定收敛速率的研究提供理论和仿真支持。Settlement and uneven settlement may occur after the completion of the airport high fi ll slope engineering.In practical engineering,due to the complex conditions of the fi eld area,various soil parameters and different fi lling heights,the settlement stability control of the airport high fill slope is mainly based on experience,and the control effect is not good.Based on ABAQUS,a numerical simulation model is established to further study the post-construction settlement rate under different dry densities and Poisson's ratios,which provides theoretical and simulation support for the study of the stable convergence rate of airport high fi ll settlement.
