在对路堤荷载作用下的格栅-桩-桩间土荷载传递机理分析的基础上,建立了桩承式加筋路堤力学计算模型.采用极限平衡理论,推导了桩承式加筋路堤格栅上表面荷载计算公式.考虑格栅下部桩间土的支撑作用,对格栅受力与变形进行分析,推导了格栅在填土荷载作用下的挠度计算公式,从而可确定桩土荷载分担比.将该方法计算结果与已有测试结果进行了对比,表明该方法的计算结果与测试结果相差不超过6%.
Based on the analysis of the soil-to-soil load transfer mechanism under the action of embankment load, the mechanics calculation model of the piled reinforced embankment is established. By using the limit equilibrium theory, the pile-supported reinforced embankment grid On the upper surface of the load calculation formula.Considering the support role of the soil between the lower part of the grid grille on the force and deformation analysis, derivation of the grille under the fill of the deflection deflection formula, which can determine the load-sharing ratio of pile soil The comparison between the calculated result and the existing test result shows that the calculated result and the test result differ by no more than 6%.
