摘要
为了确保基坑开挖和支护施工的顺利进行,通过对施工现场进行严密的实时监测,并利用承台基坑的监测结果指导施工过程,使施工过程合理化、信息化。研究结果表明:使用监测系统能够及时发现问题并反馈信息,在一定程度上降低了人员的劳动强度,可有效避免支撑轴力超过设计强度所导致的支承破坏和整个支护体系失稳,对施工进度及施工质量有着积极的影响。
In order to ensure the smooth progress of foundation pit excavation and support construction,the construction process was rationalized and informationized through rigorous realtime monitoring of the construction site of foundation pit and using the monitoring results to guide the construction process.The results show that using the monitoring system can promptly find the problems and get feedback information and therefore reduce the labor intensity of personnel;the support failure caused by the axial force of support exceeding the design strength and the instability of the entire support system can be effectively avoided,which has a positive influence on the construction schedule and quality.
