摘　　要：在有地面沉降的区域进行高速铁路建设时,施工沉降监测直接反映出的沉降量往往无法体现出其真实沉降量。通过研究基准点、工作基点和监测点的相对关系,按照时空内插模型将低频的起算基准数据加密与监测点周期一致,从而叠加区域沉降去除附加沉降得到真实沉降,为轨道平顺性评估分析提供可靠数据支撑。During the construction of the high speed railway in land subsidence area,the settlement of construction monitoring directly reflected is usually unable to represent its true settlement. By studying the relative relationship between the benchmark point,working point and monitoring point,encrypt the low-frequency benchmark data in according with monitoring points cycle with the time-spatial interpolation model,thus appending land subsidence and removing the additional settlement to obtain the real settlement,so as to providing authentic data for the evaluation and analysis of track regularity.
