| 摘 要： | 某高速铁路北京至济南段地处华北平原,沿线经过的大部分地区都存在着不同程度的地面沉降。对穿越不同地面沉降速率区段的高速铁路工程,沉降观测得到的桥墩沉降量是工程沉降与区域沉降的综合体现。由于地面沉降速率在空间上是不均匀的,本文对区分工程沉降和区域沉降进行了研究,并提出了对沉降观测的改进措施。

| Abstract: | The Beijing to Jinan section of a high-speed railway is located in the Northern China Plain,along with different degrees of land subsidence.For the railway through the different sections of different land subsidence,the settlement observed is the comprehensive expression of land subsidence and engineering settlement.As the rate of land subsidence is not uniform in space,the paper studied to distinguish between the land subsidence and engineering settlement,and gave the improved observation method as solution. |
