一种新的粉喷桩处理软土地基的建模方法

A new analysis method of soil foundation stabilized in soil

针对高速公路等重大工程软土粉喷桩路基处理模型 ,在单向渗透固结理论的基础上提出了一种更符合实际情况的新的分析模型 ,给出了在均布荷载状态下对软土地基沉降量的计算方法 ,并用此方法对工程实例进行了计算分析 。

This paper provided a new mathematical model of roadbed where underlying clay was stabilized by deep soil mixing(DSM) and jet grouting.This model was based on the consolidation theory, considering the new initial condition and boundary condition.The model is adopted in the real engineering experiment to predict the roadbed settlement and the result is in good agreement with the experimental data.
