摘　　要：以单粒径的标准砂和具有一定级配的砂卵石为填料,对土工拉筋带进行室内拉拔试验,得到在不同填料、不同含水量和不同压实度条件下筋-土间的似摩擦系数的变化规律,为加筋技术在实际工程应用中提供依据。This paper carries out indoor tensile test for geotechnical tension brace filled with standard sand of single grain size and sandstone of a certain grading and obtains the rule of changes of mimic friction factor of reinforced soil under different fillings, different water content and different compactness to provide evidence for reinforced technique in practical engineering application.

关 键 词：拉筋带 压实度 拉拔试验 似摩擦系数
