摘要
原位试验对天然地基岩土体的扰动较小,通常比室内试验能够获得更加准确的数据,是确定地基承载力的重要手段。为了提高地基检测结果的准确性,对同一天然地基土进行旁压试验与标准贯入试验对比研究。以广州某技术研发中心天然地基检验为研究对象,分别介绍了两种试验方法的操作要领,对试验获取的数据进行对比分析,结果表明,旁压试验与标准贯入试验相互补充,使得检测结果更加准确,从而增强了地基检测的可靠性。
In-situ test has less disturbance to natural foundation rock and soil,and can usually obtain more accurate data than laboratory test.It is an important means to determine the bearing capacity of foundation.In order to improve the accuracy of foundation test results,the side pressure test and standard penetration test of the same natural foundation soil are compared.Taking the natural foundation test of a technical research and development center in Guangzhou as the research object,the operation essentials of the two test methods are respectively introduced,and a comparative analysis of the data is obtained from the test.The results show that the side pressure test and the standard test complement each other,making the test results more accurate,thus enhancing the reliability of the foundation test.
