结合井睦高速公路工程项目中的山涧淤泥质土-砂混合软土地基，通过采用松木桩、CFG桩和水泥深层搅拌桩对该软基进行处理，并对这3种软基处理方案进行技术比较与经济分析，以便得到最优处理方案.研究表明：松木桩的造价在3种处理方式中是最高的，而且松木桩受处理深度和承载力的限制，它不是最佳的选择方案；在相同的条件下，CFG桩法处理地基的造价是水泥深层搅拌法处理地基的1.4倍左右，造价较为昂贵；最终确定选用水泥深层搅拌桩法加固该工程的淤泥质土-砂混合软土地基.
結閤井睦高速公路工程項目中的山澗淤泥質土-砂混閤軟土地基，通過採用鬆木樁、CFG樁和水泥深層攪拌樁對該軟基進行處理，併對這3種軟基處理方案進行技術比較與經濟分析，以便得到最優處理方案.研究錶明：鬆木樁的造價在3種處理方式中是最高的，而且鬆木樁受處理深度和承載力的限製，它不是最佳的選擇方案；在相同的條件下，CFG樁法處理地基的造價是水泥深層攪拌法處理地基的1.4倍左右，造價較為昂貴；最終確定選用水泥深層攪拌樁法加固該工程的淤泥質土-砂混閤軟土地基.

This paper is based on the mountain silt-sand mixed soft soil foundation of Jing-mu highway project. Through technical comparison and economic analysis of the treatment programs of the soft soil foundation about the Pine pile, the CFG pile (Cement Fly-ash Gravel Pile) and the Cement Deep Mixing pile are made so as to select the best treatment program. The study shows that the cost of the Pine pile is the highest among the three treatment programs of the soft soil foundation which is limited by the processing depth and the bearing capacity to be chosen as the best option. Under the same conditions, the cost of the CFG pile is so much expensive as to 1.4 times that of the cement deep mixing pile. Finally, cement deep mixing pile is chosen to handle the silt-sand mixed soft soil foundation in this project.
