摘　　要：在土工合成材料加筋土工程中,土工合成材料与填料的界面作用特性是最重要的技术指标,因此利用拉拔试验研究土工合成材料与填料的界面作用特性是非常必要的。文章采用两种国产土工合成材料为加筋材料,用砂、石屑和粉质黏土为填料,通过拉拔试验比较在不同填土性质、填土密实度、筋材上覆压力及筋材表面粗糙度等情况下土工合成材料与填料的界面特性,从而得出一些有益的结论。The characteristics of interface interaction between geosynthetics and soil are the key factor for geosynthetics reinforcement engineering. Hence it is essential to quantify the interaction by pulling out tests. This paper presents the results of pulling out tests using three kinds of native geosynthetics as reinforcement materials; and using sand, rock chips and silty clay as filling materials respectively. The comparisons are made under different conditions including soil filling quality, soil filling compactness, vertical pressure and geosynthetics surface roughness. Some useful conclusions are obtained on the basis of the results.
