Research on the Comprehensive Analysis Method of Detecting Karst Roadbed Diseaseof Existing Railway |
| |
| Abstract: | Based on the karst roadbed disease section of the railway, multichannel seismic surface wave and ground penetrating radar were used to carry out physical exploration, supplemented by confirmative mobile drilling exploration for comprehensive analysis and research. The result shows that karst anomalies in the survey area can be divided into three categories, namely covered karst, buried karst and anomalies caused by disturbance of railway track, contact network, bridge and culvert; the karst development degree in the survey area is divided into karst development area, relatively developed karst area and slightly developed karst area; Karst development areas and relatively developed karst areas with small roof thickness should be given priority for renovation; the more deeply buried relatively developed karst areas and slightly developed karst sections should be strengthened monitoring. |
