A tall building completed in April, 1994 in Niigata has been supported by friction piles due to local foundation characteristics. The project gave an opportunity to monitor the foundation behavior during a period of about 3 years, as well as to perform settlement analysis by FEM which were combined Boussinesq's solution, Love's solution and beam elements. The main analytical results are : The maximum settlement of ground and foundation by premonitoring analysis was 60% larger than observed value. We considered that difference between analysis and observation was mainly due to ground water level. Because vertical stress in a ground and Young's modulus of ground are affected by ground water level. Then settlement analysis were carried out using observed ground water level and correction Yong's modulus. As a result, close agreement between observed and calculated value was obtained.
