  • The X-section pile is a kind of cast-in-place concrete pile casted by X-section steel mould. The main steps contain sinking of mould, injection of concrete and conservation. It has the advantages of high capacity, economy and convenience for construction, etc. It is therefore suitable for the soft clay ground treatment for highways and railways. Based on the large-scale model test system developed by Hohai University, the vertical load static tests are carried out. The shaft resistance and the ratio of shaft resistance to point resistance are studied. The results show that the X-section piles can improve the utilization rate of section and the resistance capacity with the same amount of concrete. This study will provide important information for further studies on various engineering characteristics of X-section piles.
