论大地感知系统与大地感知工程

摘要

本文提出了“大地感知系统”与“大地感知工程”的概念,并从地质体的特点,论述了大地感知系统的基本组成、感知要求及其相关技术,重点介绍了分布式光纤感测技术体系,总结了相关技术的感测原理和优缺点.最后,阐述了大地感知工程的内涵、需要解决的课题、相关安装和布设工艺等.论文对于大地感知系统的构建、地质工程监测和地质灾害防治具有指导意义.%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.
