青商大厦基坑围护监测方案设计 摘 要：目前，由于勘察、设计或施工不当而引起的基坑支护失效的情况经常发生，给相邻建筑、交通要道市政设施带来了极大的危害。因此，基坑围护结构的监测越来越重要。为保证青商大厦基坑围护结构的安全，对青商大厦的基坑围护结构及其周围情况进行监测，精确反应基坑围护结构的位移变化情况，并作为施工依据。本设计针对青商大厦的基坑围护结构情况及其周围环境变化情况进行设计，主要内容包括基坑围护结构沉降监测和水平位移监测的监测精度、监测网的布设方式、监测网的网型分析以及周围环境的监测，对基准点及监测点的埋设、监测路线的布设、监测仪器的选用、监测数据的处理和分析、工程预算等方面进行设计论证,保证基坑围护结构监测工作有序进行，监测精度满足工程要求。 关键词：基坑围护结构监测；沉降监测；深层水平位移监测；控制网优化；稳定性分析；周围环境监测
毕业设计（论文）外文摘要
Design of Foundation Pit Support Monitoring Scheme for the Youth Chamber of Commerce Building Abstract: At present, caused by investigation, excavation design and improper construction support failure caused by adjacent to the existing phenomenon of damage to buildings, roads, municipal facilities are not uncommon. Therefore, it is more and more important to monitor the building envelope and the surrounding environment in deep foundation pit construction. In order to guarantee the safety of Qing Shang building foundation pit enclosure structure, on the green building enclosure structure of a foundation pit and its surrounding monitoring, accurate response in the engineering construction of bracing structure of foundation pit displacement change situation, and as a basis for construction. This design mainly for green building foundation pit retaining structure and its changes in the surrounding environment of design, design and the design for the green building foundation pit retaining structure situation and changes in the surrounding environment, the main contents include retaining structure of foundation pit settlement monitoring and measuring the horizontal displacement monitoring accuracy, monitoring network layout, network monitoring network analysis and environment monitoring, design and demonstration of the datum point and monitoring point embedding, monitoring line layout, monitoring instrument selection, monitoring data processing and analysis, engineering budget.Finally completed the green commercial building foundation pit support monitoring program design. Keywords: Monitoring of foundation pit retaining structure; Settlement monitoring; Deep horizontal; displacement monitoring; Control network optimization; ability analysis; Environmental monitoring
