... ABSTRACT If excavation works in front of a temporary retaining wall is performed in loose sand with high ground water level, a boiling problem would be induced at the site. Due to excessive ground settlement induced by the boiling at excavation bottom, severe damage may take place...

... of soil to the mobilized frictional angle. Parametric studies on trench length, internal frictional angle of soil, ground water level and slurry level were performed. Analytical resu1ts indicate that shallow depth within three meters below grade is the most critical part. It is observed...
