Static loading tests of five nodular piles and four non-nodular piles were performed in Tianjin soft clayey soil in which measurements of axial force and movements were made. Distribution of shaft resistance and load-movement curves for pile head and pile toe are presented in this paper. The applicability of modular piles to soft soil and their effectiveness are also discussed. Based on the comparison, it is concluded that nodular piles have an advantage over non-nodular piles mainly in contributing to shaft resistance. Dynamic testing was also conducted through R.P.T. for evaluation the service load of tested piles.
