中文摘要: |
土工格栅由于具有强度高、低延伸率、与土体具有良好的接触特性等特点而作为土体加筋的主要材料。在土体中适当位置加入土工格栅等土工合成材料可以有效地减少其竖向沉降和侧向变形。通过非线性有限元分析,研究了在顶部不同荷载工况下,加筋前后土体塑性区大小及分布、水平应力及变形、竖向应力及沉降规律。 |
英文摘要: |
With such good characteristics as high strength, low elongation and good contact with soil, geogrid is used as the main reinforcement material. After placed in the appropriate location in soil, it can effectively reduce the vertical settlement and lateral deformation of soil. According to the non linear finite element analyses under different load operating conditions at the slope top, the plastic zone size and distribution, the level stress and deformation, the vertical stress and settlement rules are studied and evaluated. |
