| 摘 要： | 从时空连续性角度研究了高速铁路施工过程中路基沉降观测及数据分析过程,对京沪实施《细则》中的路基沉降观测频次表进行了改进,确保其时间连续性与空间继承性。并在此基础上提出"三分原则"对路基沉降进行分段、分层、分时评估,以期指导路基信息化施工。

| Abstract: | Subgrade settlement observation and data analysis procedure of high-speed railway during construction are studied from the point of time-space continuity.Subgrade Settlement Frequency Table in the Rules for Beijing-Shanghai Railway is improved to ensure time continuity and space succession.Based on this,trisection principle is put forward,which means to evaluate subgrade settlement according to different section,different layer and different time so as to guide information-based construction. |

| Keywords: | subgrade settlement observation time-space continuity trisection principle evaluation |
