摘要

摘要: 为解决高路堤涵洞纵向不均匀沉降所带来的病害问题,基于纵向沉降控制的高路堤涵洞调荷机理,利用有限元软件研究涵洞填土与地基土特性以及不同EPS板参数对涵顶垂直土压力和涵底土体沉降的影响,通过离心模型试验探讨涵洞纵向铺设EPS板对高路堤及涵洞的沉降的影响。通过数值模拟计算,分析不同EPS板模量、铺设范围、厚度以及地基处理范围对高路堤涵洞纵向沉降差减少率的影响。研究结果表明：①填土模量与泊松比对涵顶垂直土压力及涵底土体沉降的影响不显著;②随着地基土模量与泊松比的增加,涵底土体纵向沉降趋于均匀分布;③数值仿真与离心模型试验成果得出,沿涵洞纵向分层铺设EPS板时,涵洞纵向调荷效果最佳;④通过数值模拟计算得到了基于纵向沉降控制的高路堤涵洞调荷设计计算方法。

Abstract: In order to solve the disease problem caused by longitudinal uneven settlement of high embankment culverts, based on their vertical settlement control mechanism, the influences of the characteristics of culvert fill and foundation soil and different EPS plate parameters on the vertical soil pressures at culvert top and the soil settlements at culvert bottom are studied by means of the finite element software. The influences of longitudinal EPS plates on settlements of high embankment and culvert are studied through the centrifugal model tests. Through numerical simulation, the influences of different moduli, laying ranges, thicknesses of EPS planes and ranges of ground treatment on the reduction rate of longitudinal settlement difference of high embankment culverts are analyzed. The results show that: (1) The influences of modulus and Poisson's ratio of the fill on vertical soil pressures at culvert top and soil settlements at culvert bottom are not significant. (2) With the increase of modulus and Poisson's ratio of foundation soil, the longitudinal settlements of soil at culvert bottom tend to uniform distribution. (3) The results of numerical simulations and centrifugal model tests indicate that the longitudinal laying of EPS plates along the culvert leads to the best effectiveness of longitudinal load adjustment of culverts. (4) Through numerical simulation, the design method for high embankment culvert loads based on longitudinal settlement control is obtained.
