STEEL-PLASTIC TENON GEOGRID AND ITS INTERACTION CHARACTERISTICS WITH BACKFILLS

  • 摘要: 本文在钢塑土工格栅之上辅以凸榫设计,研制出一种新型的土工格栅结构类型,即钢塑凸榫土工格栅。将钢塑土工格栅和钢塑凸榫土工格栅分别与多种不同类型的典型填料进行室内直剪试验和室内拉拔试验,证明了凸榫的设置有利于筋土界面性能的改善。通过对凸榫土工格栅的破坏模型进行理论分析,推导了凸榫格栅与岩土体间界面抗剪强度的理论公式。通过与室内试验结果对比分析表明,该理论公式求得的内摩擦角值基本符合实际,而黏聚力则不符合实际,凸榫对黏聚力的贡献值建议取2~7kPa。
