目的在建筑物的沉降测量过程中,由于受诸多因素影响,使得观测的建筑物沉降数据不够精确,以至于影响最终判断。因此,设计一套合理的观测方案成为当前沉降观测工程的研究热点。方法以宿州学院实训大楼为研究对象,结合现场布设控制网并设计技术路线,依据精密仪器得到沉降观测数据,利用Excel等软件对数据进行分析和处理。结果实验结果表明,宿州学院实训大楼在整个观测周期中各观测点累计沉降量的最大值为17.9mm,累计沉降量的最小值15.6mm,未发生引起建筑物破坏的沉降,相邻点沉降差最大值为1.8mm,未发生明显的不均匀沉降,观测末期第112d沉降速率最大值为0.004mm·d~(-1),结合本工程地质情况综合分析,该建筑物沉降已趋于稳定。结论实验基本完成了预期观测任务,对建筑物的安全稳定性做出了精确的判断。 Purpose In the process of settlement measurement of buildings, due to many factors, the observed data of settlement of buildings are not accurate enough to affect the final judgment. Therefore, designing a set of reasonable observation scheme has become the research focus of current settlement observation project. Methods Based on the actual training building in Suzhou University, the control network was laid out on the spot and the technical route was designed. The settlement observation data were obtained according to the precision instruments. The software was used to analyze and process the data. Results The experimental results show that the maximum accumulative settlement of each observing site during the whole observation period is 17.9mm and the minimum accumulated settlement amount is 15.6mm. There is no settlement caused by building damage and adjacent settlement The maximum value of the difference is 1.8 mm, and no obvious uneven settlement occurs. The maximum sedimentation rate at the 112th day of the observation period is 0.004 mm · d -1. Combined with the geological conditions of the project, the settlement of the building has tended to be stable . Conclusion The experiment basically completed the expected observation task and made accurate judgment on the safety and stability of the building.
