In this paper

the performance of a novel technology—Brillouin optical frequency domain analysis（BOFDA）was tested and analyzed on the basis of experiments

and its spatial resolution

test accuracy and repeatability are 20 cm

±2×10-6 and ±4×10-6

respectively;Secondly

based on the tests

the comparison between brillouin time domain analysis and brillouin frequency domain analysis was conducted

and the reason of strain transition section was revealed.Thirdly

by comparing with traditional strain gauges measurements and theoretical calculations

we adopted the BOFDA to the equal intensity beam to verify the excellent test performance in the strain measurement.At last

the possible problem of BOFDA′s application in the monitoring of disaster prevention and mitigation project

such as temperature compensation and cable protection

was discussed and the corresponding solution is also presented.
