S3：It compares to determine：
Test information obtained by step S2 is compared with the standard reference information obtained by step S13, if met pre-
One of fixed criterion then judges that the fence upright stability test is unqualified.
Further, in step S1, the acceleration transducer is to be horizontally mounted, magnetic bases vertically highway axle
Line.
Further, in step S2, the power hammers hammering positions into shape in tested the upper end of the column near position of mounting hole, direction
For horizontally outward and perpendicular to highway axis.
Further, in step S3, the underproof standard of the judgement fence upright stability test includes：
A) in the case where exciting force difference is little, amplitude is obviously bigger than normal compared with standard reference information；
B) time domain waveform is irregular, and the rate of decay is slow, and die-away time is long；
C) transmission function formant is appeared in compared with low-frequency range；
D) transmission function spectral line is irregular, burr is more.
The beneficial effects of the present invention are：Present invention is implemented as this is low, detection operation has not only facilitated but also quick, and detects institute
The time of cost is short, disclosure satisfy that different location, the needs that the corrugated beam barrier security performance scene of different road conditions is detected in real time,
Highway operation management unit can be helped to grasp the safety guarantee performance of administrative road section traffic volume safety devices, also can be used as quality surveillance
Unit exercises supervision to guardrail construction quality a kind of means of selective examination.
