某高速公路软土路基沉降速率的预测

On prediction of settlement rate of soft roadbed on some express road

以某沿海高速公路软土路基施工为例,采用指数法进行沉降速率预测,拟合情况良好,沉降速率的变化趋势基本一致,反算的地基参数与地质勘察结果较为吻合,为动态控制工期提供了依据,取得了较好的经济效益,可供同行施工学习。

Taking the soft roadbed of some beach express road as an example, the paper adopts the index method to predict the settlement rate, which has better fitting situation, and has the consistent change tendency of the settlement rate, and the calculated parameters are consistent with the geological observatory results, so it provides the reference for the dynamic control of the construction period, achieve better economic benefits and can be learned by peers.
