既有线挡土墙安全性综合评估方法的应用

Application of Comprehensive Evaluation Method of Structural Reliability on the Retaining Wall in Conventional Rail

挡土墙作为路基工程的重要组成部分,在使用一定年限后多会出现不同程度的病害。通过现场勘察和地质雷达检测综合评估其安全性,直观地反映病害程度,划分安全等级,可及时地发现线路安全隐患并为下一步采取措施提供依据。

The retaining walls are the important parts of subgrade engineering, after worked for certain years, most of them have appeared a series of diseases, which has seriously affected the safety and easy to have accidents. A method to comprehensive evaluate the retaining walls structural reliability is proposed in this paper, using ground penetrating radar and site investigation technology. This method can reflect the degree of diseases more intuitionistie, divide the safety grade, and then the hidden trouble of line can be found in time, to provide evidence for subsequent measures.
