| Abstract: | This paper made a preliminary study on the effect of CRD method of civil air defense tunnel on the surface based on the monitoring data, the Matlab software and the mining subsidence theory. The impacted zone was confirmed. The settlement curve''s inflection point and its characteristics were found. The lower velocity zone and higher velocity zone of settlement variation were distinguished. These achievements could be referenced for the design of relevant construction and monitoring of the old tunnels. |
