摘　　要：土工合成材料加筋土工程中 ,土工合成材料与土的界面作用特性是关键的技术指标。文章以土工格栅为加筋材料 ,以风积砂为填料 ,通过直剪试验和拉拔试验研究土工格栅与风积砂土的界面作用特性 。The characteristics of interfaction between geosynthetics and soil are the key technical indicators in the reinforced earth of geosynthetics. Based on the results from direct shear test and pull\|out test by using the geogrid as reinforced material and aeolian sand as filler, the characteristics of interfaction are analyzed in this paper, thus providing some data for some projects which use aeolian sand.\;
