通过广东省怀集至三水公路水泥搅拌桩复合地基处理的工程实例,介绍了＂四搅四喷＂施工方法在水泥搅拌桩复合地基处理中与常规＂两搅一喷＂施工方法的软基处理效果的对比,通过轻型静力触探、无侧限抗压强度、标准贯入、单桩承载力、复合地基承载力等试验,阐明施工方法、土质等对水泥搅拌桩施工成桩质量的影响。在水泥搅拌桩施工完成后,根据路基沉降观测数据对本工程水泥搅拌桩的处理效果进行了评价总结。
通過廣東省懷集至三水公路水泥攪拌樁複閤地基處理的工程實例,介紹瞭＂四攪四噴＂施工方法在水泥攪拌樁複閤地基處理中與常規＂兩攪一噴＂施工方法的軟基處理效果的對比,通過輕型靜力觸探、無側限抗壓彊度、標準貫入、單樁承載力、複閤地基承載力等試驗,闡明施工方法、土質等對水泥攪拌樁施工成樁質量的影響。在水泥攪拌樁施工完成後,根據路基沉降觀測數據對本工程水泥攪拌樁的處理效果進行瞭評價總結。

Based on cement mixed pile composite foundation practice at HuaijiSanshui Highway in Guangdong province, in this paper, the comparison of treatment results between the "four mixes four spraying" and normal "two mixes one spraying" construction methods for cement mixed pile composite foundation treatment has been introduced, through the "static cone penetration test", "unconfined compression test (SPT)", "standard pone- tration test", "single pile bearing capacity test" and "complex soil base test", the influence of the construction method and soil properties to the quality of cement mixed piles has been explained. The treatment effect of the cement mixed piles has been evaluated and summed-up on the basis of embankment settlement observation data after completion of cement mixed piles.
