交通荷载作用下软土路基沉降的数值模拟

Numerical Modeling of Soft Soil Roadbed Settlement under Traffic Load

阐述了交通荷载作用下软土路基沉降情况,分析换填二灰土后公路路基的工后沉降,采用大型有限元软件ADINA建立平面模型,对换填前后交通荷载作用下的路基沉降进行了数值模拟,研究结果表明,换填二灰土可有效控制路基沉降,起到了加固路基的作用。

This paper describes the settlement of soft soil roadbed under the traffic load and analyzes the settlement of soft soil roadbed after changing with lime-- ash soil. The planar model was established by using large finite element software ADINA to carry out the numerical modeling of soft soil roadbed settlement under traffic load before and after changing with lime--ash soil. The results have shown that changing with lime-ash soil is able to effectively control the roadbed settlement and strengthen the roadbed.
