在基坑施工过程中,支撑结构轴力往往是基坑工程现场监测的主要内容之一,其作用在于避免支撑轴力超过设计强度导致支撑破坏引起整个支护体系失稳或破坏。但在实际工程中,由于基坑本身力学性质复杂,加之工程设计估算的简化和现场施工存在诸多偶然因素的不确定性,使基坑支护结构监测数据和设计提供数值存在一定的差异。本项研究通过理论结合试验分析,对目前混凝土支撑轴力监测进行探索和讨论,以期解决目前基坑支撑轴力监测出现的问题,提高监测数据的准确性。
During the construction process of foundation pit, the axial force of supporting structure is often one of the main contents of on-site monitoring of foundation pit engineering. Its function is to prevent the supporting system from breaking or destroying the whole supporting system due to the support strength being reduced when the supporting axial force exceeds the designed strength. However, due to the complex mechanical properties of the foundation pit itself, as well as the simplification of engineering design estimates and the uncertainty of many occasional factors in on-site construction, there is some discrepancy between the monitoring data and the design values provided by the foundation pit support structures. In this study, theoretical analysis and experimental analysis are carried out to explore and discuss the current monitoring of axial force of concrete support, in order to solve the problems that occur in the monitoring of axial force of foundation pit support and improve the accuracy of monitoring data.
