摘　　要：通过对天津市滨海新区某道路K13＋840断面进行沉降观测资料分析，应用灰色理论建立等时距GM1．1路基沉降预测模型，并通过应用matlab程序语言编制模型计算程序，以实现对海相软土路基沉降变形特性研究，并运用预测分析结果指导路基施工，防止因路基沉降造成路面结构破坏。希望通过对归纳结果的分析，形成一套适应于滨海地区路基沉降预测方法，对于节约工程建设使用成本和延长公路使用寿命具有重要意义。According to the analysis of the settlement observation data of Tianjin Binhai New Area K13＋840 road, equal interval GM1.1 subgrade settlement prediction model was established by application of gray theory, model calculation program was compiled by matlab programming language. To prevent pavement damage caused by subgrade settlement, this paper formed a subgrade settlement prediction methods adapted to the coastal areas. The study of marine soft soil embankment settlement deformation and using forecast analysis results to guide construction are important to save construction cost and prolong service life of highway.
