This paper discussed the design and analysis of bridge foundation subjected to load of train with four codes, namely AASHTO code, British Standard BS Code 8004 (1986).The Chinese National Standard (CNS, 2002) and Chinese code (TB10002.5-2005). The study focused on the design and analysis of bridge’s foundation manually with the four codes and found which code is better for design and controls the problem of high settlement due to the applied loads. The results showed the Chinese codes are costly that the number of reinforcement bars in the pile cap and piles is more than those with AASHTO code and BS code with the same dimensions. Settlement of the bridge was calculated depending on the data collected from the project site. The vertical ultimate bearing capacity of single pile for three codes was also discussed. Another analysis by using the three-dimensional Plaxis program of finite elements and many parameters were calculated. The maximum values of the vertical displacement were close to the calculated ones. The results indicate that the AASHTO code was economics and safer in the bearing capacity of single pile, while the Chinese code (CNS, 2002) gave a good indicator of the risk to foundation settlement.


Key word: Bridge engineering, settlement and bearing capacity, codes for design.
