标准贯入试验在砂桩桩体质量检测中的应用

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。

The Application of Standard Penetration Test in the Quality Detection of the Sand Pile Body

Standard penetration test is an original position testing method of geotechnical engineering,which can be used for quality detection of sand pile testing.It can comprehensively reflect the construction quality of the sand pile and evalu- ate the multiple effectiveness of foundation stabilization.Associated with example of engineering,the application of stan- dard penetration test in quality detection of the sand pile body has been probed and analyzed in this paper,maters that needs more attention and consideration have been concluded.Meanwhile,the dealing method for the testing point of the pile body after the test has been put forward,the actual tested result correction and the result application has been dis- cussed,and some potential problems during the sand pile construction has also been summed up in this paper,which can be a reference for engineering and technology persons.
