| 摘 要： | 返包式土工格栅被广泛应用于路堤的加固.本文以某高速公路路堤断面为背景,利用Plaxis有限元软件建立二维分析模型,并结合现场实测数据分析了返包式加筋路堤水平土压力、垂直土压力和格栅拉伸应变等在施工期间的变化规律.发现路基填土在采用土工格栅加强后,有效的调整了不同层位处土体的水平土压力和垂直土压力,施工期间格栅的拉伸应变也一直在合理的范围以内.

| Abstract: | Geogrids reinforced soil embankment without concrete panel is widely used in the reinforcement of embankment .Based on the section of an expressway , a two-dimensional analysis model was established with the finite element software Plaxis .The transformation law of the horizontal earth pressure , the vertical earth pressure and the tensile strain of geogrids during the period of construction were analyzed with the measured data in field test .After reinforcing by the geogrids , the horizontal earth and vertical earth pressures of the embankment were adjusted effectively .And the tensile strain of geogrids is in a reasonable range during construction . |
