摘　　要：本文以邢临高速公路模块式土工格栅加筋土挡墙工程为依托,根据现场试验监测数据,分析以石灰土为填料的模块式土工格栅加筋土挡墙,在施工期及竣工后的工作特性,得出了墙体基底应力、墙背侧向土压力、拉筋变形等分布特征,确定了加筋土挡墙潜在破裂面的位置及破坏形式。Through the project of geogrid reinforced field test, this article has made researches on retainting wall in Xing-Lin highway and the the working characteristics of the geogrid reinforced retainting wall made up of calcic soils in the time of construction and finishing, obtaining the distribution characteristics of the wall foundation pressure,the back wall lateral earth pressure and the tension steel deformation. Drawing out the location of the potential fractured surface in reinforced retaining wall.
