| 摘 要： | 通过分析卸载控制方法，提出软基路堤超载预压工况应使用工后沉降法控制卸载，参照国外相关资料提出了考虑侧向变形影响的工后沉降估算方法，根据实测资料建立了预测沉降的BP神经网络模型，通过实例说明了提出的超载卸载控制方法的可靠性。

| Abstract: | Based on the analysis of unloading control methods, it is suggested that the post-completion settlement method should be applied to unloading control in overload pre-consolidation of embankments with soft soil foundations. A method for estimating post-completion settlement, considering the impact of lateral deformation, is provided, with reference to foreign literature. A BP neural network model for settlement predication is established on the basis of observed data. The reliability of the unloading control method presented is verified by an engineering example. |
