基于Origin的填方体沉降预测研究分析

Analytical Research on Settlement Prediction of Embankment Based on the Origin

山岭地区路基结构多采用填挖方式构建,填方体稳定性受到填土材料、压实工艺以及环境等综合因素影响,其工后沉降变形是影响填方体稳定性的重要因素。为此,借助数值分析工具Origin,通过构建指数预测模型对填方体沉降变形情况进行分析,结果显示建模预测精度均控制在毫米级别,满足工程建设中对填方体整体稳定性的把控要求。

The roadbed structure in the mountainous area is mostly constructed by filling and excavation.Therefore,the stability of embankment is affected by factors such as fill materials,compaction technology and environment.The post-construction settlement and deformation is an important factor affecting the stability of the embankment.With the help of Origin,an numerical analysis tool,the settlement and deformation of the embankment is analyzed by building an exponential prediction model.The results show that the modeling prediction accuracy is controlled at the millimeter level,meeting the requirements for overall stability of embankment in engineering construction.
