挤实砂桩加固饱和软粘土岸坡地基的应用研究

通过实际工程现场原位试验观测，对于挤实砂桩加固饱和软粘土岸坡地基的效果进行了多方法的研究，并对观测结果进行了理论分析。结果表明：挤实砂桩加固饱和软粘土岸坡的作用效果明显，形成砂桩复合地基，提高了岸坡土体的抗剪强度，增加了地基的抗滑能力。

Study on Use of Sand Compaction Piles to Improve Foundations of Saturated Soft Clay Bank Slopes

With field testing and measurements for a practical project, the result of improvement of a foundation of saturated soft clay bank slope with sand compaction piles is studied with multiple approaches and the measured results are theoretically analyzed. The results of the study and analysis indicate that the effect of the sand compaction piles to improve saturated soft clay Dank slopes was remarkable and a sand-pile composite foundation was formed, thus enhancing the shear strength of the soil mass in the Dank slope and increasing the sliding resistance of the foundation.
