| 摘 要： | 在软土地基上修建高等级公路,工后沉降不能满足要求时,加固土桩(水泥搅拌桩和旋喷桩)是常用的一种深层处理方法。该文通过分析计算发现,当桩长与桩间距平方的比值最小时,地基处理费用最少,这种组合称之为加固土桩处理软基桩长与桩间距的经济组合。

| Abstract: | When the settlement after treatment can not meet the requirements on the soft soil subgrade to build the high-class highway, the reinforcing soil pile (cement agitating pile and rotary spray pile) is a common deep-level treatment method. Through the analysis and calculation, the article finds the subgrade treatment cost is the lowest when the square ratio of the pile length with the pile distance is the minimum. This kind of the combination is named as the economical combination of length with distance of reinforcing soil pile to treat soft subgrade. |
