Abstract:There are some differences between the design of pile foundation of Macao and the technical code for building pile foundations in Mainland of China. Taking a car park for heavy vehicles in Macao for example,four bored piles were tested with self-balanced load method. The similarities and differences of the two codes in tip resistance of bored piles,side friction resistance of bored piles,design safety factor and upside load effect coefficient were discussed. According to the results of the four-pile tests with self-balanced load method,the axial compression and anti-pulling behaviors of the bored piles were analyzed with the two codes,respectively. Furthermore,the results indicate that the value of the bored pile tip resistance is the same as the precast pile¢s value with the Macao code. However,the value is three or four times higher than the actual one. Thus,the rationality of the test program and the test results were doubted. In order to overcome the disadvantages of Macao code in bored pile tip resistance,the designers,owners and contractors of the project from different countries or regions consulted for several times. Finally,the test results were modified to be rational. These experiences may provide the lessons and references to the similar international cooperating projects.
