Performance of Corrugated Metal Pipe (CMP) Culverts during Past Earthquakes
To evaluate culvert performance during earthquakes, we reviewed reconnaissance reports from six earthquakes and conducted field investigations in areas shaken by three of those earthquakes. Hundreds of CMP culverts were in place in strongly shaken areas. Lack of reported or observed damage to all but ten of these structures indicate that CMP culverts generally perform very well during strong earthquake shaking. Of the ten damaged culverts, all but one were in areas of ground failure caused by liquefaction or slope instability. The one culvert not in an area of ground failure suffered minor damage because of increased lateral pressures cracking a head wall and slightly deforming the pipe inlet. Damaging ground failures included embankment penetration into softened or liquefied foundation soils, lateral spread, ground oscillation and slope instability. Diameters of the examined culverts ranged from 0.45 m to 3.6 m.
