摘　　要：公路高路堤支挡新结构是由薄壁挡墙、对拉钢筋、条形基础和填土组成,其内部受力复杂。由于排水的需要,在本结构内部设置了盖板涵,由于本结构构造及内部受力复杂,致使盖板涵的设置比常规路堤盖板涵的设置难度大。为了弄清盖板涵在这种特殊结构中的受力特点,本文应用有限元方法对公路高路堤支挡新结构盖板涵进行了详细的三维数值计算,得到了新型支挡结构盖板涵沉降及内部应力,并分析了该盖板涵沉降的变化规律和内部应力的分布规律。The structure mentioned in this paper is consisted of thin retaining wall, anchored steel, foundation and filling soil and there is a complicated forced state inside the structure. Because of the request of drainage, a box culvert is set inside. In order to understand the mechanics feature of the box culvert inside this special structure, in this paper, the finite element method is applied to the 3D numerical calculation of the box culvert in a new type supporting structure of highway embankment and the changing regulation of settlement and the distribution regulation of inner stress are analyzed in the box culvert.
