Abstract
Two corrugated steel pipe culverts were chosen in north connection highway project of the Fourth Nanjing Yangtze River Bridge. From testing the strain conditions of corrugated steel pipe culvert under different soil fill heights, the fiber Bragg grating sensors were set in the inner or outer of corrugated steel pipe culverts. Corrugated steel pipe culvert has the capacity of larger formation. So in the soft soil area, using its good ductility can solve the problem of uneven settlement.
