Abstract: With the continuous growth of science and technology level, more and more advanced technical means are applied in the construction of building engineering, which provides reliable guarantee for the construction quality of engineering projects. The technology of bored pile can eff ectively improve the stability and safety of the building foundation structure, and the type of technology chosen will be diff erent due to diff erent geological conditions in the practical application, therefore, the choice of technical means in diff erent areas will have a great gap, should be based on the specifi c construction situation, choose scientifi c and eff ective construction methods to ensure the smooth construction of the project. Based on this, this paper will discuss and analyze the concrete application of bored pile technology.
