Methods in Detecting Typical Embankment Defects During Operation Period
Subgrade is required to be stable enough to provide a reliable bearing capacity during operation time. Excessive deformation caused by instability usually leads to pavement damages, especially for high embankments, soft soil embankments, and seasonal frozen soil embankments. In Ji Lin Province, a deformation monitoring project is obtaining real-time data, reflecting stability of embankments during operation time. Through a simple analysis of data, it provides a way to investigate the defects of the structure, which can be adopted as a basis of a maintenance planning. The problem of in-situ monitoring during operation period is data remote transmission. In dealing with the problem, a Data Auto-collection and Remote Transmission System (DARTS) has been built in Song Yuan Highway Monitoring Project. And GPR has been considered as a significant method in detecting unequal settlement defects, including soil freezing, soil loosing, and soil disengaging.
