对经编格栅和玻纤格栅加筋粘性土进行不固结不排水的三轴压缩试验。试验结果表明,在粘性土体上布置格栅筋材,都能提高土体强度,但不同的筋材,其加筋效果是不一样的,经编格栅加筋土的加筋效果要优于玻纤格栅加筋土。加筋层数越多,加筋效果越好;随着加筋土应力增加,加筋土抵抗变形的作用才能得到更充分发挥,土体加筋效果更明显。不同筋材的加筋土,其粘聚力与内摩擦角的变化规律不一致;玻纤格栅和经编格栅加筋粘性土的加筋效果与砂土不同,不仅表现在粘聚力的增加上,还表现在内摩擦角的增加上。加强筋条结点连接的牢固性,能够提高加筋效果。 Uncoupled and undrained triaxial compression tests on warp-knitted grids and glass fiber grid-reinforced clay. The test results show that the geogrid reinforcement can be used to increase the strength of the soil on the clay soil. However, the reinforcing effect of different geogrids is not the same. The reinforcement effect of the geogrid reinforced soil is better Reinforced in the glass fiber reinforced earth. The more the reinforcement layer, the better the reinforcement effect. With the increase of the stress of the reinforced soil, the role of the reinforced soil in resistance to deformation can be fully exerted, and the soil reinforcement effect is more obvious. The different reinforced tendons, its cohesion and internal friction angle of the variation is inconsistent; glass fiberglass and warp grille reinforcement clay effect is different with the sand, not only in cohesion Increase, but also in the increase of the internal friction angle. Reinforcing the firmness of the junctions of the bars can improve the reinforcement effect.
