摘要

通过室内小比尺模型试验，模拟了两种边坡坡比、两种格栅以及3种加筋层数共计10种边坡结构在坡顶荷载作用下边坡和土工格栅的变形规律。研究了土工格栅加筋参数对路堤边坡结构性能的影响。试验结果表明，加筋能大幅提高边坡的稳定性和承载能力，并得出了土工格栅埋在土中的力学特征，对工程实践具有一定的指导意义。

Abstract

Based on the small scale model tests

the structural performances of ten reinforced and unreinforced slopes were studied

which include two slope angles

1:1 and 1:1.2; two kinds of geogrids

Tensar 40RE and 80RE; and three different reinforcement layers

zero

one and three layers. Under a strip footing load near the slope crest

the deformations of slopes and geogrids were modeled. The coefficients of reinforcement how to affect the structural performance of embankment slopes were carried out; and the mechanical character of geogrids in soils was derived. It is shown that the geogrid will improve the stability and the capacity of the slope.
