摘要：

采用COMSOL Multiphysics有限元软件建立高铁有砟轨道路基三维注浆模型，以注浆压力、注浆深度、注浆下倾角度、注浆管间距为主要参数进行了数值模拟研究。研究结果表明：上表面通量可很好地表征冒浆情况，上表面通量与注浆压力具有显著正相关性，注浆压力每增大0.1 MPa，通量线性增大约0.05 kg/m2·s；注浆深度、注浆下倾角度、注浆管间距的增大会使表面通量减小；注浆压力对冒浆影响最为显著；采用袖阀管分段和施加上盖层的联合注浆方法能有效控制高铁路基注浆过程中的冒浆问题。

Abstract:

COMSOL Multiphysics finite element software was used to establish a three-dimensional grouting model of high-speed railway ballast-track subgrade. Taking grouting pressure， grouting depth， grouting downward inclination angle and grouting pipe spacing as the main grouting parameters， a numerical simulation study was conducted. The results showed that： The upper surface flux can be used to characterize the amount of grouting. In the process of grouting， the amount of surface mud spillover is significantly positively correlated with the grouting pressure. When the grouting pressure increases by 0.1 MPa， the flux linearly increases by about 0.05 kg/m2·s. The surface flux decreases with the increase of grouting depth， downward inclination angle and grouting pipe spacing. Grouting pressure has a significant effect on the grouting effect. The combined construction method of sleeve valve tube section and upper cover layer is adopted， which can effectively control the mud spillover problem.

Key words: high speed railway, ballast track, mud spillover, finite element simulation, construction optimization
