Abstract:In this paper, first we analyze the basic data of cross-fault flow deformation monitoring in the Shanxi area. There is a great monitoring blind spot, the monitoring site monitoring means is single, most of the sites are not arranged as rings, and there are a lot of bedrock mixed monitoring sites in the cross-fault flow deformation monitoring. Then, the monitoring effectiveness is evaluated from the aspects of monitoring environment and earthquake response efficiency. There are serious environmental interference factors in individual monitoring sites, seriously affecting the quality of monitoring data. Finally, the monitoring optimization of cross-fault flow deformation is discussed and some suggestions are put forward to improve the capability and level of cross-layer flow deformation monitoring in this area.
