摘　　要：结合某沿排渠道路设计项目,对行车荷载作用在挡墙的不同间距位置时的受力情况进行分析,得出车墙距离与挡墙受力情况的规律。按照一般排渠挡墙墙高4 m的断面提供了一个计算参考,当行车荷载作用距离墙背小于3 m时,尤其需要注意加载后对挡墙的不利影响,需对挡土墙进行加固或者新建。Combined with a design project of road along a drainage channel,the force situation of the driving load at different spacing positions of the retaining wall is analyzed.The law of the distance between the vehicle wall and the force situation of the retaining wall is obtained.A calculation reference is provided according to the general 4-m section of drainage channel retaining wall.When the distance between the driving load and the wall back is less than 3 m,particularly,it is necessary to pay attention to the adverse impact on the retaining wall after loading,and to reinforce or build a new retaining wall.
