The Application of Spatial Interpolation Methods for a Substation Foundation Settlement
This paper introduces the theoretical foundations of the mobile simulation method,inverse dis-tance weighting method,and linear interpolation method.Taking the relocation and expansion project of the Danhe Power Plant in Jiaozuo as a case study,the paper compares the foundation settlement calcula-tions obtained from these three spatial interpolation methods with the measured engineering data.The re-sults show that in the early stages of construction,where the load is relatively small and evenly distribu-ted,the mobile simulation method is more practical for engineering applications due to its simplicity and ease of calculation.In the mid to late stages of construction,as uneven load distribution increases differ-ential settlement,the inverse distance weighting method provides a reasonable simulation of settlement at obscured points.
