基于Usher-Spillman模型的软土地基沉降预测研究

某软土地区采用真空—堆载联合预压法处理路基,为了了解最终沉降量,建立了Usher-Spillman模型,以实际测量数据为基础,对沉降量进行了预测,发现基于模型的推测值与实测值较为接近,说明了使用该模型在该地区对真空—堆载联合预压法加固软土路基进行沉降预测是可行的。

Soft soil foundation settlement prediction based on Usher-Spillman model

In construction of a soft soil foundation, the vacuum and preloading method was used to consolidate the soft soil in test section. Take the measured data as the basis for the establishment of the Usher-Spillman model and the final settlement forecast. By comparison with the meas- ured data shows that, the projected value based on the Usher-Spillman model are close to the measured values, and have got the result that the Usher-Spillman model was feasible in the reinforcement of soft soil foundation settlement prediction by vacuum and preloading method.
