摘要
本文介绍了柔性测斜仪的工作原理,对某软基深基坑项目中柔性测斜仪自动化监测的应用成果进行了分析研究。根据施工工况分析了柔性测斜仪测试成果的可靠性,结合人工测斜成果验证了其测试成果的准确性,通过坑周地表断面竖向位移的监测进一步验证了柔性测斜仪在深层水平位移自动化监测中的可靠性与准确性。研究结果表明,柔性测斜仪可以在软土地基深基坑深层水平位移测试项目中推广应用,尤其适用于周边环境复杂的深大基坑,可实时、准确而可靠地反馈基坑重要的变形信息。
The working principle of flexible inclinometer is introduced, and the application results of automatic monitoring of flexible inclinometer in a soft ground deep excavation project are analyzed and studied. According to the construction conditions, the reliability of the test results of the flexible inclinometer is analyzed. Compared with the manual inclinometer results, the result accuracy of flexible inclinometer is verified. Through the surface settlement monitoring results around the excavation, the reliability and accuracy of the automatic monitoring results of deep horizontal displacement are further verified. The research results show that the flexible inclinometer can be promoted to monitor the horizontal displacement of deep excavation project in soft ground, especially in the deep and large excavation with complex surrounding environment, which could feed back important deformation information of the excavation in time, accurately and reliably.
