摘　　要：重力式挡土墙广泛用作高速公路边坡支挡结构,如何鉴定挡土墙的综合质量是当前需要解决的问题。本文提出基于地质雷达的重力式挡土墙质量检测结果并结合挡土墙的稳定性验算和安全验算结果的综合评估方法,对公路挡土墙综合质量的安全进行分类评估。工程应用表明该综合方法可在高速公路重力式挡土墙安全评估中应用。为大面积开展高速公路重力式挡土墙安全评估提供了工具。The gravity retaining wails are broadly used in the highway construction, and their quality detection and safety assessment become serous. A method based on GPR quality detection results is presented and applied for the gravity retaining wall~ quality detection and safety assessment in this pa- per. By this method, the highway the gravity retaining walls are detected quickly and their safety are e- valuated in three classes. The project example proved that this method is a rapid tool for the massive re- taining walls＇ quality detection and safety assessment in the highway engineering.
