| Abstract: | This paper aims at the improvement of the capacity of saturated sandy loam against liquefaction without drain after pile-driving.The effects of the content of clay-size parti- cles in soil,the grading of the soil,the precipitation and the pile-driving procedure on the capacity of the soil are analysized.The conclusion is that with proper grading and some specified pile-driving procedure,the capacity of the soil against liquefaction improves significantly |
