摘　　要：本文通过对第四系风积沙地基的流动特性以及挡土结构物静止不动、风积沙土体处于弹性平衡状态时,风积沙土体对挡土结构物的静止土压力分布情况的研究,探究了维持挡土结构物稳定、增大与地基整合面相接触的自由面摩擦力的作用原理,并利用数值模拟软件FLAC对挡土结构进行了模拟,重点对其位移云图、应力云图以及应变云图进行了分析。This paper analyzes the flow characteristics of the Quaternary aeolian sand foundation and the static soil pressure distribution of the aeolian sand soil on the retaining structure when the retaining structure is stationary and the aeolian sand soil is in an elastic equilibrium state.The study explored the principle of maintaining the stability of the retaining structure and increasing the friction of the free surface in contact with the integrated surface of the foundation,and used the numerical simulation software FLAC to simulate the retaining structure,focusing on the analysis of its displacement cloud diagram,stress cloud diagram and the strain cloud chart.
