In the high embankment construction using high water content clay that is the large scale, belt drains were adopted as drainage in embankment and a good result was obtained by effect of promoted consolidation of belt drains. From the observation result, horizontal displacement became to be small remarkably compared with vertical displacement, during execution and after execution. As a cause, it was thought that reinforcement effect was worked to restrict transformation of embankment. Therefore, plate type strain gauge was installed to belt drains laid in embankment and stress to work to belt drains was measuredand reinforcement effect was confirmed. In the other, observation carried out a displacementof surface of embankment by expansion measure and a transformation of embankment inside by settlement plate and inclinometer.This paper reports the result of examination into drainage effect and reinforcement effect of belt drains arranged stagger in embankment from the observation result.
