摘要
以武汉绿地国际金融城深基坑止水帷幕声纳渗流检测为例,采用了声纳渗流原位测量技术,以大数据源解析成像,在三维空间显示地下连续墙的施工质量缺陷与地下水的流速、流向、流量、渗透系数对应的渗漏通道的坐标位置,有针对性地提供防渗堵漏的措施与方案。为深基坑的渗控治理、渗漏风险评价提供了原创的水文地质参数检测的新方法与技术手段。
This paper takes Wuhan Greenland International Financial Center as an example, in order to introduce how the sonar seepage flow detection method is used in the construction of deep foundation excavation. The sonar seepage measurement procedure uses the situ technology. The relationship between the construction quality of the underground continuous wall and the groundwater seepage field is shown on the three-dimensional visualization chart. By analyzing the enormous amount of hydro geological measurement data, the water curtain leakage channel and the path of the coordinates will be easily located, then an anti-seepage plugging measures and programs will be customized. So potential risk of the pipeline leaking disaster is under control.
