中文摘要：

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。

英文摘要：

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.
