“…Geosynthetic tubes have been widely used for coastal protection, dike construction, flood control and waste sludge dewatering in many countries (Leshchinsky et al, 1996;Saathoff et al, 2007;Katoh et al, 1994;Lee, 2009;Yan and Chu, 2010;Shin and Oh, 2007;. Sometimes, the geosynthetic tubes have to be placed on soft ground.…”

“…In these cases, the ground settlement will influence the performance of the structures made by the geosynthetic tubes. So far, most of the methods for the design and calculation of the geosynthetic tubes assume the foundation soil is rigid (Leshchinsky et al, 1996;Plaut and Suherman, 1998;Cantr e and Saathoff, 2011;Yan and Chu, 2010;Chu et al, 2011;Malik and Sysala, 2011;Plaut and Stephens, 2012;Guo et al, 2014a,b). The only method to analyze the geosynthetic tube by considering the deformation of soft ground is to use the Winkler model (Plaut and Suherman, 1998;Plaut and Klusman, 1999;Guo et al, 2011).…”

The 2011 Tohoku earthquake off the Pacific coast of Japan (M w ¼ 9.0) contained a huge source region of approximately 450 km by 200 km and caused extensive damage to various structures. Damage caused by the tsunami was tremendous and many lives were lost. In addition to the damage to concrete structures, seawalls were seriously damaged, probably as a result of scouring. On the other hand, some reinforced soil walls were barely damaged, although they were inundated by the tsunami. This paper briefly reviews the reinforced soil walls in Japan and then summarises the seismic performances of approximately 1600 walls in the 2011 Tohoku earthquake. It also reports some case histories for the reinforced soil walls that were subjected to the direct impact of the earthquake (shaking) and the tsunami. Although seismic motion was much higher than the design value for a wide area and the impact of the tsunami was not considered in the design, fewer than 1% of the walls were seriously damaged and more than 90% showed no damage. However, some damage was found at the backfill and facing panels where the soil was not properly covered and protected against erosion by the tsunami.

Geosynthetic tube has been used for dike constructions on soft ground. We need methods to design geosynthetic tubes that rest on deformable foundation. In this paper, 2D analytical and numerical methods are proposed to analyze the stress and deformation of the impermeable geosynthetic tubes resting on deformable foundation. The analytical method is proposed by using the 1D consolidation relationship or the e-log-p curve as an approximation. As the stress-strain relationship is nonlinear, this method is better than the Winkler method. The vertical pressure distribution in the soil is calculated using the Boussinesq equation. Numerical analyses are also carried out to evaluate the accuracy of the proposed method and good agreement between the results from the analytical method those from numerical methods was achieved.
