摘　　要：地下工程沉降数据通常采用分析离散检测点的方法，绘制沉降预警云图，从而对地表的沉降情况进行直观的判断。该文对插值算法进行了比较，采取kriging算法并提出了一种可行性方案。该方案能够利用较少测量点进行插值从而生成一定区域内的彩色沉降预警云图，应用此方案对北京某地铁施工区域进行了沉降预警云图的绘制，Underground engineering analysis of settlement data uses detect discrete point method, rendering the settlement warning cloud, which on the surface for the settlement of intuitive judgments. In this paper, use interpolation algorithm to take kriging algorithm and pre- sents a feasibility plan. The program can make use of fewer measurement points must be interpolated to generate the region early settlement cloud of color, the application of this program on the Beijing subway construction of a regional early warning to the settlement of the drawn image.
