在加宽路基处理问题的研究中，根据新旧路基在含水量、压缩性、承载力等工程性质的特点，普遍采用水泥搅拌桩对加宽路基做加固处理。近年来地基处理采用新型的双向水泥搅拌桩。从两种搅拌桩加固路基的试验入手，对比分析了两者对已有结构的影响程度、新旧结构的差异沉降以及工期影响。通过工程监测验证了双向水泥搅拌桩各方面都优于普通水泥搅拌桩。
在加寬路基處理問題的研究中，根據新舊路基在含水量、壓縮性、承載力等工程性質的特點，普遍採用水泥攪拌樁對加寬路基做加固處理。近年來地基處理採用新型的雙嚮水泥攪拌樁。從兩種攪拌樁加固路基的試驗入手，對比分析瞭兩者對已有結構的影響程度、新舊結構的差異沉降以及工期影響。通過工程鑑測驗證瞭雙嚮水泥攪拌樁各方麵都優于普通水泥攪拌樁。

Within the study on treatment of widened subgrade, cement mixing pile is commonly used to reinforce the widened subgrade in accordance with the characteristics of the new and old subgrades in moisture content, compressibility, bearing capacity, engineering performance. In recent years, new bidirectional cement mixing pile is adopted in foundation treatment. Setting about the tests concerning the subgrade reinforced by two kinds of mixing pile, a comparison and analysis on how the both influence the existing structure, the different settlements of new and old structures and the construction period is carried out. By the construction monitoring, it is proved that the bidirectional cement mixing pile is superior to general cement mixing pile.
