摘　　要：通过对具有不同含水率、不同土工格栅加筋层的粘土进行了三轴压缩试验,测定了土工格栅加筋土体的抗剪强度指标。分析了土工格栅加筋粘土体的内摩擦角和粘聚力随含水率、加筋层的变化规律,得出了有土工格栅加筋粘土的重要结论。Triaxial compression tests were made on clay with different moisture content and different reinforced geogrid layers. The shear strength of clay reinforced with geogrid was determined, the change laws of internal friction and cohesion of clay reinforced by geogrid with moisture content and reinforced geogrid lavers were analyzed, and some significant conclusions about clay reinforced with geogrid were drawn.
