摘　　要：重力式挡土墙的面坡坡率和背坡坡率与其抗滑及抗倾覆稳定性有着密切的联系。调整挡土墙的面坡坡率和背坡坡率,使其满足稳定性验算是工程中采用的一般方法。为了研究探索能够满足稳定验算且结构型式较优的挡土墙,通过设置不同坡率的挡土墙,分析论证面坡坡率和背坡坡率对挡土墙稳定性的影响程度,进一步指导实际工程。研究结果表明:面坡坡率对挡土墙的抗滑及抗倾覆稳定性影响程度高于背坡坡率。若要提高挡土墙的稳定性,在同等条件下,优先调整面坡坡率更为合理。The surface slope rate and back slope rate of gravity retaining wall are closely related to its anti-slip stability and overturning stability.Adjusting the surface slope ratio and back slope ratio of retaining walls to meet the stability calculation is a general method used in engineering.In order to find better retaining walls structure which can keep it stable and to guide the engineering practice,different slope rates of retaining walls were set up,and the impact of surface and back slope rates on the stability of retaining walls was analyzed and demonstrated.The results show that the influence of surface slope rate on the anti-slip and overturning stability of retaining wall is more serious than that of back slope rate.To improve the stability of the retaining wall,it is more reasonable to prioritize adjusting the slope rate of the surface under the same conditions.
