Abstract
This paper reports the reason of the adaptation and the proceeding of the construction of a gabion soil wall structurally continued with reinforcement applied for high embankment on the sloped ground in expressway construction, and also reports the influence of the damage of the reinforcement due to the rolling compaction of the back-filling material, and the results of observations during construction and after construction. This time, we adopted this reinforced soil wall with gabion as the wall material, expecting the drainage effect of groundwater inside the reinforced soil wall backside and embankment. In construction, it was difficult to hold the shape of the gabion to be used as a wall material. So we solved this problem by using a frame for holding the shape. Regarding the damage of the reinforcing material, the degree of damage was suppressed by installing a nonwoven fabric on the upper surface of the reinforcing material. And we got the results of field observation about the displacement of the wall material was sufficiently satisfying the specified construction control value.
