摘要
在南京地铁某工程中,采用地震波CT和井地地震技术检测坍塌基坑注浆加固范围。研究表明,地震波CT和井地地震技术对注浆加固体均有较好的反映,通过两种技术方法的对比分析,划分出注浆加固的范围,并给出不同深度下注浆加固范围的水平切面。
In a project of Nanjing Metro, seismic wave CT and borehole seismic technology were used to detect the grouting reinforcement range of collapsed foundation pit. The research shows that seismic wave CT and borehole seismic technology have a good reflection on grouting and solid. Through the comparative analysis of the two technical methods, the scope of grouting reinforcement is divided, and the horizontal section of the grouting reinforcement scope at different depths is given.
