抄録: A pile net method is one of the pile driving works for reinforcing soft ground. It was developed in 1976 as a countermeasure for high organic soil deposit in Hokkaido, Japan. The application of the pile met nethod to the Ariake clay ground has been carried out since 1981 at three districts in the Rokkaku River system on the Saga plain. In the Kutsugu district, the pile net was driven near the rail road embankment of JR Sasebo line in order to study the effect of restraining the lateral flow of the soft ground. Due to the heavy rainfall which occurred in the north-middle part of Kyushu on 2nd July 1990, 9 points of the embankments in the Rokkaku River system was broken and overtopping extended to 11, 300m. Therefore, fill raising of 1.6m in height will be executed in this area in 1994. This paper discusses the judgement taken for the reinforcement for the above plan by means of synthetic analysis, consisting of bearing capacity, slope stability and stress-coupling finite element analysis. The results of the analysis show that the plan will be successfully executed using only small sized filling of 1m in height at inland.
