土工格栅是一种常用的路堤加筋材料,具有高强度、低延伸率等特点。为了研究在软土地基上填筑昔格达土路堤的加筋效果,利用有限元软件Abaqus,建立不加筋模型进行计算分析,确定出合理的加筋部位,然后在此基础上建立加1~3层筋的3种加筋模型进行计算,并与不加筋结果进行对比分析。结果表明:昔格达土路堤加筋虽然对软土地基的竖向位移影响不大,但加筋能有效抑制侧向位移的发展,增大了路堤边坡的稳定性。研究成果对软土地基上昔格达土加筋路堤的设计和施工有一定的借鉴意义。
Geogrid is a commonly used embankment reinforced materials, with high strength, low elongation and other characteristics. In order to study the reinforcing effect of embankment of Xigeda soil embankment on soft soil foundation, the finite element software Abaqus was used to calculate and analyze the reinforced model without embankment, and the reasonable reinforced area was determined. Based on this, ~ 3-layer tendons of three kinds of reinforced models were calculated and compared with non-reinforced results. The results show that although the reinforcement of Xigeda earth embankment has little effect on the vertical displacement of soft soil foundation, the reinforcement can effectively suppress the development of lateral displacement and increase the stability of embankment slope. The research results have some reference to the design and construction of Xigeda soil reinforced embankment on soft soil foundation.
