Research Status and Prospect of strain monitoring method of geotechnical engineering

摘要

This paper summarizes the importance of strain monitoring, points the characteristics and the main difficulty in strain monitoring of geotechnical. From the current situation in Strain monitoring of geotechnical engineering, it analyzes and summarizes the principle and the practical application of the advantages and disadvantages of strain gauges, fiber Bragg grating and distributed optical fiber. Finally, it designs an overview of geotechnical engineering strain monitoring system, nine principles of strain monitoring system to be put forward, and the direction of geotechnical engineering is the development of strain monitoring system and application.
