ON THE GROUND SENSING SYSTEM AND GROUND SENSING ENGINEERING

In this paper, two concepts are proposed—namely, the ground sensing system and the ground sensing engineering. First, the basic composition, sensing requirements and related techniques of the ground sensing system is discussed based on the characteristics of geological media and geological materials. Then, the distributed fiber optic sensing technique is highlighted and introduced, and its technical system, sensing principles, and advantages and disadvantages are summarized. Finally, the meaning of the ground sensing engineering is elaborated, followed by corresponding installation techniques, and some issues to be addressed in this field. The implications of this paper may be of great importance for structuring of ground sensing system, geoengineering monitoring, and prevention and treatment of a variety of geological hazards.
