重载铁路高路堤沉降预测及影响因素分析
|
摘要
随着重载列车运量与运次的提高,路堤沉降增加,影响重载列车的平稳运行,因此对重载铁路路堤的沉降预测显得十分必要.依据巴准重载铁路典型工况,在Abaqus有限元非线性分析基础上,利用长期沉降经验公式,提出重载铁路路堤沉降预测模型,并对路堤年沉降量进行参数分析.研究结果表明,重载铁路路基填土沉降在第一年迅速发展,由于道床沉降的线性增加,路堤总沉降近似线性增加;道床设计参数对路堤沉降的影响较基床表面参数影响更大,减小道床厚度或提高道床刚度可有效降低路堤沉降.
With the increase in the volume and the delivery times of heavy-haul railway,the settlement of embankment developes rapidly,thus the method of the settlement prediction of heavyhaul embankment is essential.According to the typicle conditions of Ba-Zhun Railway,a settlement prediction model which is based on empirical formulae and Abaqus nonlinear dynamic finite element method is proposed.And the parameter analyses on yearly settlement volume of embankment are carried out.The results show that the settlement of heavy-haul railway embankment rises rapidly in the first year,the total settlement of embankment is approximately linear because of the linear increase of the settlement of the ballast;the effect of ballast parameters on embankment settlement is greater than that of embankment surface layer; decreasing ballast thicknessand increasing its modulus can promote the drop in embankment settlement.
