Abstract: The uneven foundation of a piling engineering project, which is composed of loose fill and mid-weathered mudstone, needs treatment due to uneven settlement of the project. The initial consideration is to improve the soil foundation, but the range of improvement is difficult to determine. In view of this, stability calculation is carried out for the built body by using numerical simulation method. Results reveal that only parts of the soil foundation needed to be reinforced without changing the whole soil foundation. The stability of the built body was greatly improved by reinforcing parts of the soil foundation. The analysis results in this paper provide meaningful reference for similar projects.
