Abstract

The underground basement of a building is highly affected by anomalous seepage problems. Detection of seepage-prone regions through and around buildings becomes a need in other to sustain their stability. It is of great importance as well to have targeted remedies. However, traditional methods for examining these areas are often destructive and expensive, compelling the use of non-destructive geophysical techniques. This work aims to utilize and demonstrate the hands-on application of ground penetrating radar (GPR) and self-potential (SP) methods as an innovative combination to study seepage-prone zones in the basement of a building. Simulated responses of various seepage zones have been generated based on several significant factors. For better visualization, all 2D radargrams of a block were combined to produce a 3D model using GPR Slice software to distinguish various features at different depths. Higher positive SP values show the presence of high moisture or seepage-prone regions. Conclusively, the combined geophysical method of GPR and SP is trustworthy for conducting a quick and effective inspection of seepage-prone regions and probable source points for detailed characterization of the basement of a building. Keywords: GPR, SP, Geophysical methods, Seepage, Basement.
探测建筑物地下室易渗漏区的综合地球物理勘测
建筑物的地下地下室受异常渗水问题的影响很大。为了保持建筑物的稳定性,必须对建筑物内部和周围的渗水区域进行检测。有针对性地采取补救措施也非常重要。然而,检查这些区域的传统方法往往具有破坏性,而且成本高昂,因此必须使用非破坏性地球物理技术。这项工作旨在利用和展示地面穿透雷达(GPR)和自电位(SP)方法的实际应用,将其作为一种创新组合来研究建筑物地下室的渗漏易发区。各种渗流区的模拟响应是根据几个重要因素生成的。为了更好地实现可视化,使用 GPR Slice 软件将一个区块的所有二维雷达图组合起来生成三维模型,以区分不同深度的各种特征。较高的正 SP 值表明存在高湿度或易渗漏区域。总之,GPR 和 SP 的组合地球物理方法对于快速有效地检测渗漏易发区域和可能的渗漏源点,以详细分析建筑物地下室的特征是值得信赖的。关键词GPR、SP、地球物理方法、渗流、地下室。
