摘要:

建筑物差异沉降易引发结构倾斜、构件损坏甚至垮塌,严重威胁结构使用安全与寿命。针对传统调控技术精度低、安全性差、速度慢、控制难的问题,研发基于监控大数据的差异沉降实时协同调控技术。该技术通过多传感器监测系统采集竖向承载构件倾斜、沉降、应力变化等多源大数据,经实时智能纠偏控制系统分析,精准确定抬升点位、抬升量及封桩压力等参数,实现差异沉降的动态协同调控与基础加固。加固纠偏完成后,通过 M10 自流平砂浆压力注浆处理抬升孔隙,保障筏板基础与地基土可靠传力。工程实践表明,该技术将建筑物向南最大倾斜率由 4.7‰调整至 1.1‰,向西最大倾斜率由 6.0‰调整至 1.5‰,使其满足相关规范要求,保障了建筑物在复杂施工环境下的安全稳定。

The differential settlement of buildings is easy to cause structural inclination, component damageand even collapse,which seriously threatens the safety and service life of structures. Aiming at theproblems of low precision, poor safety, slow speed and difficult control of traditional coordinated controltechnology, a real-time coordinated control technology of differential settlement based on monitoring bigdata is developed. The technology collects multi-source big data such as inclination, settlement and stresschange of vertical bearing members through multi-sensor monitoring system. Through the analysis of real-time intelligent correction control system, the parameters such as lifting point, lifting amount and sealingpressure are accurately determined, and the dynamic coordinated control of differential settlement andfoundation reinforcement are realized. After the completion of the reinforcement and correction, the upliftpore is treated by M10 self-leveling mortar pressure grouting to ensure the reliable force transmissionbetween the raft foundation and the foundation soil. The engineering practice shows that the maximuminclination rate of the building to the south is adjusted from 4.7‰ to 1.1‰, and the maximum inclinationrate to the west is adjusted from 6.0‰ to 1.5‰, so that it meets the requirements of relevant specificationsand ensures the safety and stability of the building in complex construction environment.
