Intelligent deformation monitoring method for deep and large foundation pit construction
The invention belongs to the technical field of foundation pit support monitoring, provides an intelligent deformation monitoring method for deep and large foundation pit construction, and solves the problems that an existing traditional measurement method is greatly limited by space and time, and real-time monitoring of foundation pit support is inconvenient. A plurality of monitoring points are arranged at the position where a foundation pit is prone to deformation, and a plurality of datum points are pre-buried outside the foundation pit engineering pressure propagation range; installing a laser displacement sensor at the monitoring point, and installing a photosensitive plate at the reference point; the laser displacement sensor uploads detected displacement change data of the monitoring point to the monitoring platform; a displacement alarm threshold value of each monitoring point is preset in the monitoring platform, and the monitoring platform compares the displacement change data of the monitoring points with the preset displacement alarm threshold values and judges whether to output alarm information or not. The measurement method is slightly limited by the space of the foundation pit, data of each monitoring point can be mastered in real time, the position of supporting deformation of the deep foundation pit is visually reflected, and early warning and alarm information is output.
本发明属于基坑支护监测技术领域，提供了一种深大基坑施工智能监测变形的方法，解决了现有传统的测量方法受空间和时间限制较大，基坑支护实时监测不便的问题。在基坑易发生变形的位置设置多个监测点，在基坑工程压力传播范围外预埋设多个基准点；在监测点处安装激光位移传感器，在基准点处安装感光板；激光位移传感器将检测到的监测点的位移变化数据上传至监测平台；在监测平台中预设各个监测点的位移报警阈值，监测平台对比监测点的位移变化数据与预设的位移报警阈值并判断是否输出报警信息。本发明的测量方法受基坑空间限制小、能够实时地掌握每个监测点的数据，直观反映深基坑支护变形的位置并输出预警和报警信息。
