Monitoring and early warning method, monitoring instrument and monitoring and early warning system for deformation condition of dead zone of deep foundation pit support structure
The invention discloses a monitoring and early-warning method, a monitoring instrument and a monitoring and early-warning system for the deformation condition of a dead zone of a deep foundation pit support structure, and the monitoring and early-warning method comprises the following steps: building a Mada model of the deep foundation pit support structure based on design requirements; performing stress analysis on the deep foundation pit enclosure structure, determining a monitoring key area of the enclosure structure, and selecting at least one monitoring point in the monitoring key area; monitors are installed between the reference datum of the deep foundation pit bottom sealing structure and all the monitoring points; correcting the monitoring key area and each monitoring point; position coordinates of the correction monitoring points before and after deformation and bending deformation data of the correction monitoring points are collected in real time; and based on the bending deformation data and an early warning threshold value pre-stored in the server, monitoring and early warning are carried out on bending deformation of the enclosure structure. The method has the beneficial effects that the monitoring key area and the position of each monitoring point of the enclosure structure can be determined, the bending deformation of the enclosure structure in the horizontal direction can be monitored in real time, and the risk in the construction process is reduced.
本发明公开了一种深基坑围护结构盲区变形情况的监测预警方法、监测仪及监测预警系统，所述监测预警方法包括以下步骤：基于设计要求，建立深基坑围护结构的迈达斯模型；对深基坑围护结构进行应力分析，确定围护结构的监测关键区，在监测关键区选定至少一个监测点；在深基坑封底结构的参考基准面与各监测点之间安装监测仪；对监测关键区以及各监测点进行校正；实时采集校正监测点变形前后的位置坐标以及各校正监测点的弯曲变形数据；基于弯曲变形数据和服务器内预存的预警阈值，对围护结构的弯曲变形进行监测及预警。本发明的有益效果是：能确定围护结构的监测关键区和各监测点的位置，能实时监测围护结构水平方向的弯曲变形，减少施工过程中风险。
