文章以非饱和压实黄土室内模型试验为研究切入点,结合公路交通路基工程的具体情况,对高填黄土路堤的受力和沉降规律进行了理论分析研究,建立了在路堤填方的同时综合考虑非饱和压实黄土应力、变形和时间的计算模型,提出了高填路堤沉降的计算公式,为高填路堤施工预留沉降高度提供了理论依据,可有效指导设计与施工。
In this paper, taking the indoor model test of unsaturated compaction loess as research entry point, combined with the specific conditions of highway traffic embankment engineering, the paper analyzes the stress and settlement law of high fill loess embankment and establishes the theory of simultaneous embankment filling Considering the calculation model of stress, deformation and time of unsaturated compacted loess, the formula of settlement of high embankment is proposed, which provides a theoretical basis for reserving the settlement height of high embankment, which can effectively guide the design and construction.
