Zones disturbed by Metro construction may affect the safety of Metro operation and surrounding buildings. In the paper, the principle and characteristics of SSP seismic scattering technology are presented, so as to find an effective method to explore the zones disturbed by Metro construction and to estimate the effect of grouting reinforcement. The application of SSP technology in Tianshuiyuan Middle Street Section of Line 14 of Beijing Metro is illustrated, which verifies the effectiveness of SSP technology in the exploration of zones disturbed by Metro construction and in the estimation of the effect of grouting reinforcement. Conclusions drawn are as follows: 1) The grouting zones in the SSP image take the form of high velocity anomalies, while the disturbed zones in the SSP image take the form of low velocity anomalies; 2) The locations and patterns of the disturbed zones and grouting reinforcement zones can be determined on basis of the distribution of the high velocity anomalies and low velocity anomalies in the SSP image; 3) SSP technology, which has such advantages as strong interference resistance, deep exploration depth and high resolution, is suitable for exploring disturbed zones and estimating grouting reinforcing effect.
