The fiber grating sensing technology is a new testing technology

which has a large number of advantage.The testing application about FBG technology on stabilizing pile model test is introduced.Firstly

the FBG sensors is calibrated with the common electricity sensors in stabilizing pile

and the relation formula about them is gained

which is about 1.143×10

-6

/nm.Then

the FBG sensors are used in the experiment.The test results show that not only the exact state of stabilizing pile stress distribution in different situation are obtained

but also many of experiences and needing attentive issues are obtained as well

which is a useful reference in similar testing.
