摘要
该文介绍了移动拟合法、反距离权重法、线性内插法的理论基础,结合焦作丹河电厂异地扩建工程,利用三种空间插值方法计算基础的沉降量与工程实测数据进行了对比分析.结果显示:工程建设前期荷载量较小且分布较为平均,移动拟合法因结构简单、计算方便,更易于在工程中应用;建设中期和后期,因荷载的不均匀分布导致差异沉降增大,利用反距离权重法来模拟被遮挡点位的沉降量比较合理.
Abstract
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.
