标准贯入试验作为岩土工程中一种原位测试方法,可以应用于砂桩桩体质量检测,并能较全面地反映砂桩的施工质量和评价复合地基加固效果。本文结合工程实例,对采用标准贯入试验方法用于砂桩桩体质量检测进行探讨分析,总结了试验过程中的注意事项,提出了桩体试验点位置的试验后处理方法,讨论了实测数据修正和成果运用问题,并归纳了砂桩施工时可能存在的问题,为相关工程技术人员提供参考。 As a in situ testing method in geotechnical engineering, the standard penetration test can be applied to the quality inspection of sand pile, and can more fully reflect the construction quality of sand pile and evaluate the reinforcement effect of composite foundation. In this paper, with the engineering examples, the standard penetrating test method is applied to the quality inspection of sand-pile body, the precautions during the test process are summarized, the post-processing method of the position of the test-point of the pile body is put forward, the measured data Amendments and results of the application of the problem, and summed up the possible problems of sand pile construction for the relevant engineering and technical personnel to provide a reference.
