摘要
河道挡墙式堤防,在正常使用情况下,会产生老化、破坏等现象。本文以鹏城河挡墙为例,研究地质雷达法、高密度电法、贯入法在既有结构挡墙安全检测中的应用。结果表明:地质雷达法、高密度电法可以在不影响结构的情况下进行无损检测,贯入法可以获取挡墙的抗压强度,从理论计算角度对挡墙稳定性进行定量评价。三种方法结合使用,可以对挡墙结构作出安全、可靠、快速的评价,可为类似工程提供参考。
The river retaining wall dike suffers from aging,damage and other phenomena under normal use.Pengcheng River retaining wall is adopted as an example in the paper to study the application of geological radar method,high-density electrical method and penetration method in the safety detection of existing structure retaining walls.The results show that the geological radar method and high-density electrical method can be used for nondestructive testing without influence on the structure,and the penetration method can be used for obtaining the compressive strength of the retaining wall,and quantitative evaluation of the stability of the retaining wall from the perspective of theoretical calculation.A safe,reliable and rapid evaluation of the retaining wall structure can be made by the combination of the three methods,thereby providing reference for similar projects.
