| 摘 要： | 对土工格栅加筋碎石土进行了系统的试验研究。结果表明：加筋复合体受力变形条件、加筋层间距及土料性质是影响碎石土加筋效果的重要因素；加筋能明显提高碎石土强度，减小变形；格栅的加筋机理服从准粘聚力原理，其加筋作用可分为格肋阻力及格栅对界面碎石土的咬合摩擦力两部分，张力膜效应只有在某些特定条件下才起主要作用。

| Abstract: | Systematic tests are made for the geogrid reinforced stone. The results show that the stress strain condition of geogrid reinforced body, distance of geogrid interlayer and stone properties are of important factors of reinforcement. The stone strength is obviously increased and its deformation is decreased by reinforcement. Mechanism of geogrid reinforced stone is in accord with pseudo cohesion concept. Tensiomembrane reaction is effective only under some special conditions. |
