Application of time-frequency analysis technique on NDT of ducts grouting in pre-stressed bridge

YANG Chundong(Chengde Highway Enginnering QA Center,Hebei Province Chengde Highway Engineering Lab,Chengde 067000,China)  
Grouting defects affect the bearing capacity and durability of pre-stressed concrete bridge.So the technology of NDT of ducts grouting is required.Duct acoustic time-frequency analysis technology is such an important method that it can analyze the vibration mode of the beam and duct by the distribution of vibration energy in the time-frequency field.It also can identify the P-wave,S-wave,Lame wave in different mode include the velocity.Combined with migration imaging technology,it can effectively locate the grouting defect in the duct.
