摘要
针对福建省工程地质条件差异极大的特点,如沿海深厚软土地区、滨海腐蚀环境、山区地基与岩溶地质并存等情况,且受到技术水平限制的原因,各检测标准提出的原位测试检测方法还不够全面。鉴于此,本文结合工程特点对钉形双向搅拌桩检测方法进行研究,提出采用重型动力触探试验结合钻芯法试验的方式评价桩身均匀性,为今后类似工程提供一定的参考。
Due to the marked differences in engineering geological conditions in Fujian Province,such as the coexistence of deep and soft coastal areas,coastal corrosive environments,mountainous foundations and karst geology,and limited by technical level,the in-situ testing methods proposed by various testing standards are not comprehensive enough.In view of this,this article studies the detection methods of T-shaped bidirectional soil-cement deep mixing pile based on engineering characteristics,and proposes that using a combination of Heavy-duty Power Penetration Test and Core Drilling Method Test to evaluate the uniformity of the pile body,providing a certain reference for similar projects in the future.
