荷载作用下软土地基低路堤应力应变分布规律分析

该文针对软土地基低路堤内部应力应变状况,利用有限元方法分析了不同荷载作用、不同土基强度以及不同的硬壳层厚度对低路堤内部的应力应变的影响,并探讨了不同影响因素下横向的应力应变分布状况。分析结果表明,采用低路堤设计,利用人工硬壳层等措施可以满足路用性能的要求。

Analysis of Stress Strain Distribution Law of Soft Soil Subgrade Low Embankment under Loading Role

In view of the inner stress strain situation of soft soil subgrade low embankment, the article uses the finite element method to analyze the influences of the different loading roles, the different soil foundation strengths and the different hard shell thicknesses on the inner stress strain of low embankment, and discusses the transverse stress strain distribution situations under the different influence factors. The analysis result makes clearly that the measures to use the design of low embankment and to ...
