以山区公路曲线型悬臂式挡土墙为研究对象，采用有限元分析方法，利用ANSYS软件建立1∶1的三维有限元模型，研究在重力场作用下，山区公路悬臂式挡土墙平面线形沿不同曲率半径布置时挡土墙与土体耦合作用下的力学性能。计算结果表明：和曲线型挡土墙相比，理想状态下的直线型挡土墙发生的位移和应力均达到最小值；同时曲线型挡土墙随着曲率半径的减小，挡土墙发生的径向位移及其横截面上所受应力逐渐增大。
以山區公路麯線型懸臂式擋土牆為研究對象，採用有限元分析方法，利用ANSYS軟件建立1∶1的三維有限元模型，研究在重力場作用下，山區公路懸臂式擋土牆平麵線形沿不同麯率半徑佈置時擋土牆與土體耦閤作用下的力學性能。計算結果錶明：和麯線型擋土牆相比，理想狀態下的直線型擋土牆髮生的位移和應力均達到最小值；同時麯線型擋土牆隨著麯率半徑的減小，擋土牆髮生的徑嚮位移及其橫截麵上所受應力逐漸增大。

With the curved cantilever retaining wall of the mountain road as research object,and through the finite element analysis method,this research establishes a 3D finite element model of 1∶1,using ANSYS software. Based on the model, the paper researches the mechanical properties of the cantilever retaining wall and soil coupled effect under the action of gravity,when the horizontal alignment of the cantilever retaining wall is arranged along the different radius of curvature. The results show that compared with those of curve type retaining wall,the ideal state of the displacement and stress of the linear retaining wall reaches minimum value;at the same time,with the increase of the radius of curvature,the retaining wall displacement and stress increase.
