板底脱空压浆处治路面板力学响应分析

Analysis on Mechanical Response of Pavement Slab for Slab Suspending Adopting Slab Jacking Treatment

通过建立有限元模型,研究了荷载作用下路面板底压浆面积等因素对压浆处治路面板应力及弯沉的影响,分析了压浆前后路面板相关指标的变化规律,确定了压浆处治路面板的力学状态,可为旧水泥混凝土路面板底脱空压浆处治方法的研究提供力学基础。

By building the finite element model,the affects of stress and deflection of pavement slab adopting grouting by pavement slab grouting area under loading are studied,the related indicators of pavement slab before and after grouting are analyzed,the mechanical state of pavement slab adopting grouting is defined,which can provide mechanical basis for the study of slab suspending adopting slab jacking treatment methods of old concrete pavement slab.
