管桩加固软土地基路堤减沉效果分析

Analysis of the Effect of Reducing Settlement of Embankment on Soft Soil Foundation

为分析管桩加固软土地基路堤的减沉效果,分别对管桩加固前后的软土地基路堤沉降进行计算。结果表明,管桩能有效减少软土地基沉降,加固后的路堤沉降量约为加固前的十分之一,且加固后的路堤能快速完成沉降,在施工完成后沉降相对较小。管桩桩长、桩径和桩壁厚度对淤泥质软土地基沉降均有明显影响,随着桩长、桩径和桩壁厚度增大,淤泥质软土地基路堤沉降量逐渐减少,随着桩间距的逐渐增大,淤泥质软土地基沉降量逐渐增大。

In order to analyze the settlement reduction effect of pipe pile reinforcement on soft soil embankments,the settlement of soft soil embankments before and after pipe pile reinforcement was calculated.The results showed that pipe piles can effectively reduce the settlement of soft soil embankments,and the settlement of the reinforced embankment is about one tenth of that before reinforcement.The reinforced embankment can quickly complete settlement,and the settlement is relatively small after construction is completed.The length,diameter,and thickness of the pipe pile have a significant impact on the settlement of the muddy soft soil foundation.As the length,diameter,and thickness of the pile increase,the settlement of the muddy soft soil foundation embankment gradually decreases.As the distance between piles increases,the settlement of the muddy soft soil foundation gradually increases.
