摘要

随着我国经济建设的发展

越来越多的基础设施修建在工程地质条件复杂的山区内

所形成的高填方工程往往不具备放坡的条件

因此如何解决高填方工程的稳定性已成为一项刻不容缓的课题。土工格栅加筋挡土墙因格栅材料具有特有的网孔结构

对土颗粒能产生极强的嵌固与咬合作用

在高填方工程中得到了越来越广泛的应用。本文基于有限元强度折减法建立了土工格栅加筋土挡墙的计算理论

并通过模型试验进行了验证。通过在某机场工程中的应用说明了土工格栅加筋土挡墙的适用性

以及基于有限元强度折减法进行加筋土挡墙设计计算的可靠性。

Abstract

With the development of economic construction and the extension of cities in China

more infrastructures are built in some mountainous areas with complicated geological conditions

such as topography and geomorphology.Due to the limitation of some natural conditions like steep terrain and deep-cutting gorge

the engineering with high embankment does not possess the sloping conditions.So

it is emergent to solve the problem of the stability of high embankment. The reinforced earth-retaining wall with geo-grids has special grid structure

which can strongly embed and occlude soil particles.As a result

this structure becomes more and more widely used in the high-embankment engineering.With the application and popularization of reinforced earthretaining wall with geo-grids

its design theories lag behind the practical engineering.The paper establishes the calculation theories based on FEM strength reduction and conducts model experiment to testify the theories.Through the engineering of a certain airport

the paper also proves the feasibility of reinforced earth-retaining wall with geo-grids and the reliability of conducting the calculation on the basis of FEM strength reduction.
