CFG pile composite foundation treatment technology is a widely used foundation treatment method. According to the site geological conditions of Yiquanguomao Hotel project and the actual situation of the project, the CFG pile is designed for the foundation treatment. The design and construction of CFG pile are introduced. The test results show that the application of CFG pile composite foundation treatment technology is a feasible basic scheme under the premise of ensuring construction quality in high-rise and even super high-rise buildings.
