| 摘 要： | 预应力CFRP加筋土技术是应用碳纤维增强塑料(CFRP)作为加筋材料,通过对加筋土体侧向的CFRP筋带端部进行张拉并锚固,给侧向土体施加侧向压力,进而增加土体的稳定性和强度。将这一技术应用于临长高速公路,对该试验路堤进行了沉降观测、弯沉试验测试。试验表明,该技术可以显著地提高加筋土路堤的回弹模量和加速加筋土结构沉降稳定。

| Abstract: | The technology of prestressed CFRP reinforced earth is that carbon fabrics reinforced plastics(CFRP) is adopted as a material for reinforcement.Through lateral pressure is applyed on sidewise soil by stretching and anchoring the end of CFRP strip,the stability and strength of the soil are improved.This technology is applied to Linxiang-Changsha Expressway.Subsidence observation and deflection tests for the test embankment are performed.The test results showe that this technology can improve the rebound modulus of reinforced-earth embankment and speed up subsidence stability of reinforced-earth structure notably. |
