| 摘 要： | 文章通过沉降速率法,建立沉降速率与工后沉降之间的关系式,并根据路面材料力学性能,确定其容许的最大不均匀沉降量,将其作为允许工后沉降来推算沉降速率,并依托G205宿迁段改建工程,用沉降速率法分析了位移较大的3个断面,得出其沉降速率应控制在1.2～2.3 mm/月.

| Abstract: | The relation between settlement rate and the post-construction settlement of subgrade is established using settlement rate method. The allowable maximun value of settlement is confirmed according to mechanical properties of pavement materials, which can be used as allowable post-construction settlement to calculate the settlement rate. Taking the reconstruction project of Suqian section of G205 as an example, the settlement rate method is used to analysis the three sections with relatively large displacement. The results show that the settlement rate should be controled within 1.2 to 2.3mm per month. |
