| 摘 要： | 探讨施工期路堤填筑速率对软土路基沉降和稳定性的影响,以某高速公路为例,建立断面模型,对不同路堤填筑情况下的路基沉降进行数值模拟.结果表明,填筑速率越大,沉降速率越大,过快的填筑速率会影响路基的稳定性,但对最终沉降量影响不显著.

| Abstract: | To explore the influence of the embankment filling rate on the settlement and stability of the soft roadbed,a cross-section model is established for a high way and numerical simulations of settlement are done for different embankment filling conditions.The results show the settling rate grows with the greater filling rate and too rapid a filling rate will affect the stability of the roadbed but not so much the final settlement amount. |
