Health monitoring construction method for large-span steel corridor overcrossing metro
The invention provides a health monitoring construction method for an overpass subway large-span steel corridor. The health monitoring construction method comprises the steps of deepening design and modeling deduction; tamping the foundation, and laying a roadbed plate; a jig frame is erected, and segmented hoisting is carried out; arranging a DIC speckle spot position and a strain gauge; dIC monitoring data, strain gauge monitoring data and soil pressure cell monitoring data are connected in series and summarized; comparing and correcting according to cloud picture data of a monitoring system; and after construction of the steel corridor is completed, the monitoring equipment, the jig frame and the roadbed plate are dismantled. According to the invention, the soil pressure box is buried at the lower part of the substrate to monitor and feed back the load value in real time, the construction load generated in each construction stage can be accurately monitored, the overrun is avoided, the strain gauge, the soil pressure box and the DIC detection technology are connected in series to form a system, so that the full-range and high-precision global monitoring is realized, the cloud picture is generated, the correction can be carried out in time, and the working efficiency is improved. Error accumulation is reduced, and the installation precision of the large-span steel corridor is improved.
本发明提供一种用于上跨地铁大跨度钢连廊的健康监测施工方法，包括深化设计、建模推演；地基夯实、铺设路基板；支设胎架、分段吊装；布设DIC散斑点位及应变计；将DIC监测、应变计、土压力盒监测数据进行串联汇总；根据监测系统云图数据进行对比、纠偏；完成钢连廊施工后拆除监测设备、胎架及路基板。本发明通过在路基板下部埋设土压力盒实时监测反馈荷载值，能够精确监控各施工阶段产生的施工荷载，避免超限，通过将应变计、土压力盒与DIC检测技术串联形成系统，以达到全范围、高精度的全局监测，并生成云图，有助于及时进行纠偏，减小误差累计，提高大跨度钢连廊的安装精度。
