The damage and development of the mountain lnass(rock mass)can be regarded as the course of the crack expansion that can be measured by the real-time monitoring.For this purpose,a thin cassette optical fiber rock mass crack gauge is studied.The design of its structure is given out in this paper,and its displacement performance and pressure performance is researched in the lab.Experiment results indicate that the thin cassette optical fiber rock mass crack gauge has characteristics such as reliable.practical and hish sensitive.The thin cassette optical fiber rock mass crack gauge is a better sensing monitoring equipment for the research on the deformation development and damage mechanism of the mountain mass(rock lnass)(or other rack engineering mass,such us the dam)and the early forecast.It has a good engineering application value in the field of geotechnical engineering.
