SETTLEMENT PERFORMANCE OF THE CENTRAL HOKKAIDO EXPRESSWAY BUILT ON PEAT

This paper discusses immediate engineering issues regarding the construction and maintenance of road embankments on peat deposits. For this purpose the paper reviews the long term settlement performance of 17 km long embankment sections in total of the central Hokkaido motorway in Japan, incorporating three test filling sections. The construction and maintenance strategies applied to the motorway embankment works are discussed and illustrated by means of soil profiles. Observations from the test filling sections helped the engineers to choose the extensive use of the sand drain (SD) method. The time-settlement performance of the test filling sections is discussed and visualized by curves. It is concluded that the SD treated test subsections experienced smaller settlements over a five year operation than the nontreated test subsections. Settlement related repair works were basicly to patch up a length of abrupt differential settlements, which commonly occurred at the bridge and embankment connections, and at the places underlain by box culverts.
