为研究影响压力分散型悬锚式挡土墙承载力的相关因素及耐久性评价，采用FLAC 3D软件对实体挡土墙工程进行了数值模拟仿真计算。对影响压力分散型悬锚式挡土墙承载力的主要因素进行了控制分析。数值计算结果表明：土压力呈非线性分布，并随填土高度的增加而增大；挡土墙在竖向和水平向都存在明显的土拱效应；锚杆存在最佳的设置高度和竖向间距；预应力对提高压力分散型挡土墙承载力的效果不显著；增大填料的粘聚力会提高压力分散型悬锚式挡土墙的承载力；挡土墙的耐久性好，在土体强度发生较大的衰减及水环境下仍可保持稳定。

In order to study the influencing factors and durability of bearing capacity for pressure dispersion suspend-ed-anchor retaining wall, FLAC 3D software was used to simulate retaining wall engineering. The main factors influencing the bearing capacity of the earth retaining wall were controlled and analyzed. The results show that the distribution of soil pressure is nonlinear, and soil pressure increases with the increasing of filling height. Soil anchoring effects of retaining wall is obvious in vertical and horizontal direction. Anchor has the optimal setting height and vertical spacing. Prestress has little effects on increasing the bearing capacity of the retaining wall. Filler with high cohesion can improve the bearing capacity of the retaining wall. The durability of the retaining wall is good, and the retaining wall has high stability with the environment of great soil strength attenuation and water erosion.
