摘要:

了解高喷注浆过程及其效果对于实际工程具有重要意义,而高密度电法是对其实施动态监测的一项有效手段。基于
Archie法则,对高密度电法所测得之数据进行转换、预处理和反演,可得到注浆过程各时段的电阻率以及不同时段的电阻
率剖面图。结果表明,注浆区测点的基体电阻率曲线与水泥浆电阻率变化曲线具有相似的特征,而非注浆区的测点则没有。
因而高密度电法可广泛应用于监测注浆过程,并对其效果进行检测,从而为探寻地下工程的可视化施工方式提供技术参考。

Abstract:

 To monitor the jet-grouting process and its effect is of great importance to the high pressure jet-grouting project, and the
high density electrical resistivity method  is one of  the most popularly used measures. Based on  the Archie
,
s law,  the monitoring
data are  transformed, pretreated and  inverted  to deduce  the variations of electrical resistivity with  time. Meanwhile,  the profiles
of electrical  resistivity during  the process of  jet-grouting are plotted. The  results show  that  the electrical  resistivity curves of
data points  for grouting matrix are parallel  to  those  for  the cement pastes, while  it  is not  the same  for  the non-grouting matrix.
Consequently,  this method could be widely used  in monitoring  the  jet-grouting process and detecting  its effect, which provides
some useful technological information to the visualized construction of underground projects.

Key words: high density electrical , resistivity method, high pressure , jet-grouting, dynamic monitoring, electrical , resistivity,
Archie’s law
